City recognition and the region in which the city is located is based on such an attitude. Material and Methodology: Cost-benefit analysis and some tools such as sustainability indicators and environmental issues are among other ways to promote attention to long-term impacts of the current development. FAHP model is one of the most popular multi-purpose decision making methods for situations with multiple measures. Finding: In this study, by calculating the weight and ranking of effective criteria and sub-criteria in the allocation and zoning of urban land use in 7 stages, FAHP technique has been applied. In order to formulate a sustainable solution for current and future urban development, it is necessary to have better knowledge about the adaptation of current constructed areas (including cities, suburban areas) with natural environmental factors. Discussion and Conclusion: Hence, the results are presented based on the charts as weighted results of the thematic information layers related to each of the sub-criteria (indices) are also given in the charts. The model of allocation and zoning of urban land is based on the degree of desirability in 4 classes or groups, which in the analysis of the method of high, middle and low limits of scores or each criterion scores based on the sub-criteria related to each of them are considered to determine the changes scope (changes limit) and by considering the effect of each of sub-criteria, the results are used based on the four criteria and sub-criteria related to them.

MoreDuring research patrol of 2001 ROPME, the physical parameters of sound velocity in the Persian Gulf were measured. The range of stations selected to measure these parameters included the entire Persian Gulf. However, these measurements were discrete from the study area.In this study sound speed was spatially modeled in Persian Gulf using the geostatistical analyst Arc GIS 9.2 software to prepare continuous and high validity maps of sound speed at different depths. These smart maps can be used to predict sound speed at any spatial coordinates in the study area by clicking the mouse pointer. Moreover, analysis of these maps led us to the conclusion that sound speed was highest in the shallower central parts but lowest in the eastern and western parts of the Gulf. The reason for this is the higher temperature and salinity in the central parts and the proximity of the eastern and western parts to the low-salinity waters of the Oman Sea around the Hormuz Strait in the eastern part and Arvandrood in the western part. The deeper waters also had the maximum sound speed around the Hormuz Strait and in the southern shores of the Persian Gulf where the more saline waters of the Gulf poured into the Oman Sea.

The indices used were included four main indices, water resources, land use, climate and soil and 22 related sub-indices (Soil texture, soil depth, soil salinity, soil acidity, distance from the river, water volume, surface water salinity, groundwater depth, groundwater salinity, mean annual temperature, mean minimum annual temperature, mean maximum annual temperature, minimum absolute temperature, maximum absolute temperature, mean annual rainfall, mean annual relative humidity, mean annual wind speed, shrublands around the rivers, sandy hills, Jihad Nasr lands, empty lands around the Jihad Nasr channels, empty lands around the water resources). Maps of these factors were prepared using Google Earth satellite imagery (from summer of 2017 to 2019), ground sampling (September of 2019) and available data. Eucalyptus cultivation map in Khuzestan province was also prepared from Khuzestan Natural Resources Administration and ground sampling by GPS in September of 2019. The land use map was prepared by the digitization of land use/cover using Google Earth satellite imagery from summer of 2017 to 2019. Accuracy of land use map was evaluated by 60 ground control points. The weight of effective indices in Eucalyptus wood farming potential was calculated using Fuzzy AHP. For this purpose, 30 expert questionnaires (30 expert judgments) were distributed among the scientific and operating experts of wood farming to express the importance and priority of effective factors in wood farming. Then, the mean questionnaire was obtained and it was analysed by Chang triangular fuzzy extent analysis. Based on this method, the normal weights of the indices and sub-indices were calculated using Fuzzy AHP method. Using the linear weighted combination of effective sub-indices, maps of the main indices and then a map of Eucalyptus wood farming potential was prepared. Finally, the wood farming potential map was validated by Eucalyptus cultivation map and its accuracy was evaluated in identifying the suitable areas for Eucalyptus wood farming in Khuzestan province. The results showed that among the main indices, water resources and land use had the most importance in the determination of the prone lands for Eucalyptus farming in Khuzestan province based on the Fuzzy AHP. According to the results, 12.83% of the area had very good potential and 10.47% of the area had good potential for Eucalyptus farming. The results of the accuracy assessment of wood farming potential map also showed that Fuzzy AHP with overall accuracy 82% had good accuracy in identification of the prone areas for wood farming in Khuzestan province.

Quantitive and irregular rainfall, limited surface water resources, and its absence in many parts of the country have led to the widespread use of groundwater. Today, increasing agricultural, horticultural and livestock activities on the one hand and industrial and workshop activities and population development along with population growth, on the other hand, excessive use of natural resources and expansion of industrial and agricultural activities and mass production of waste and scrap, groundwater resources are threatened. Seriously and has caused a lot of pollution. Qualitatively, most groundwater reservoirs are vulnerable to ministerial sources. Point sources of pollution from domestic and industrial wastewater and non-point sources of pollutants result from improper and excessive consumption of fertilizers and pesticides and their leaching into groundwater. Widespread groundwater pollution and the growth and awareness of human societies about the importance of these vulnerable resources have led to extensive efforts to protect groundwater. The process of regenerating aquifers on a regional scale in a reasonable time frame is not possible because groundwater flows very slowly. Vulnerability assessment is a way to zoning areas that are most prone to contamination; therefore, to prevent contamination and effective groundwater management, it is necessary to assess the vulnerability of aquifers because vulnerability can help determine practical and practical policies for the management of groundwater resources in the path of sustainable exploitation. In our country, in the last decade, the assessment of groundwater vulnerability to pollution has grown significantly and has had good results. Vulnerability assessment is a low-cost and powerful way to identify areas prone to contamination. Vulnerability assessment is a low-cost and powerful way to identify areas prone to contamination. In the Aisin plain of Hormozgan, due to its small area, low annual rainfall, and lack of water resources in this area, the use of groundwater resources is very important. Due to population growth, industrial activities and agricultural development, and the use of agricultural pesticides and chemical fertilizers in this plain and due to lack of knowledge or understanding of the exact level of groundwater vulnerability in this area, the need for rapid techniques to identify and assess vulnerabilities. It is underground in this area. The purpose of this research is was to map the vulnerability of groundwater in the Aisin plain of Hormozgan using DRASTIC and GODS methods and with the help of GIS.Materials and Methods This research was carried out by DRASTIC and GODS methods with the help of GIS. The DRASTIC method is the most important rating method for determining vulnerability, which is more common among researchers and experts and has been used. The DRASTIC method consists of a combination of seven measurable and effective hydrogeological features effective in transferring contamination to groundwater, including groundwater depth, net recharge, aquifer, soil environment, Topography, Impact of the vadose zone, and hydraulic conductivity. Aisin plain based on available data extracted from Hormozgan Regional Water Company in GIS environment and after ranking and weighing them between 1 to 10 and superimposing them, the final vulnerability map of Aisin aquifer based on the DRASTIC model obtained Came. The GODS model, which is a very simple, practical, and experimental method for rapid assessment of groundwater pollution potential, also has four characteristics of aquifer type, unsaturated area, groundwater depth, and soil type, which were used in this study. The data used in the above models were extracted from 19 piezometric wells located in Aisin plain, which were available from 1987 to 2018. In the GODS method, like the DRASTIC method for each of the hydrogeological characteristics based on the available data, in the GIS environment, a map was prepared and ranked between 1 and 5, then after superimposing them, vulnerability maps of Aisin plain with GODS model obtained.Results and Discussion Since in the DRASTIC model index, the minimum possible vulnerability is 23 and the maximum is 230; However, the results of the final Aisin aquifer vulnerability map by the DRASTIC method, which is almost the most complete indicator for assessing groundwater vulnerability, Showed that the range of DRASTIC index values is between 59 and 163. The map of this index has been extracted in 6 categories from non-vulnerability to high vulnerability. Most of the area (33.66%), which covers the northeastern parts, from the center to the south of the plain, has low to moderate vulnerability. After that, moderate vulnerability (19.29%) was located in parts of the center and northwest, respectively, and also very low vulnerability (14.75%) in parts of the south and east, in parts of the east and south without vulnerability (29 11.11%), in the northern and part of the center and south with low vulnerability (10.15%) and finally, high vulnerability (10.84%) in the central and western parts were in the next categories in terms of area. In fact, according to the DRASTIC model, most of the aquifer sections of the Aisin plain were in low and medium to medium vulnerability classes in terms of vulnerability potential. Also, the results of the GODS model showed that the study area is divided into three parts including low, medium, and high vulnerability. Most of the Aisin plain (66.83%) is in the range of moderate vulnerability with ranks between 0.5 to 0.3 And the lowest level (11.31%) is related to the high vulnerability potential with a rank of 0.5 to 0.7.Conclusion In general, in both methods, the inherent vulnerability of the Aisin aquifer has been evaluated in low to high vulnerability ranges, but the extent of expansion of their vulnerability ranges has been different and the DRASTIC model of different vulnerability zones due to more characteristics and different weights based on these characteristics are different. Contamination is more accurately identified. Manuscript profile -

Medicinal plants demand special environmental conditions, therefore, researchers and experts have special attention to land suitability evaluation and appropriately discover and assess ecological resources and finally, make feasibility studies for specific aims applying agricultural and ecological models. The present study aimed to identify effective climatological, topographic, and physical-chemical properties of soil on the habitat of the Ferula assafoetida medicinal herb, and zoning of suitable areas for cropping of these crops by means of Geographical Information System (GIS) in the Chatrod region of Kerman province. In the first step, the ecological requirements of Ferula assafoetida identified for determining scientific resources and thus, classified to provide thematic maps. Thematic maps also prepared and categorized by sampling the soil from the surface area at 14 points. The examined parameters included precipitation, temperature, altitude, sand, silt, clay, lime, pH, electrical conductivity, potassium, saturation, phosphorus, organic matter, and nitrogen. Finally, by integrating and matching the weighted maps in GIS software, the zoning of the habitat of the Ferula assafoetida extracted. The results of the zoning showed that Ferula assafoetida was in four zones (very suitable, suitable, moderate and poor) in terms of land suitability. Approximately 4826 hectares (16.9%) of the Chatrod region had highly suitable for growing the Ferula assafoetida herb. It is because of the specific characteristics of this area, such as low electrical conductivity, low acidity, high organic matter, and the height of 1900 to 2500 meters was. However, approximately 6819.6 hectares (23.8%) of the area of land evaluated as unsuitable zones because of low rainfall, high altitude and organic matter to grow of Ferula assafoetida.

Being placed on the Alpine - Himalayan orogeny belt and the presence of active geologic and plateau have all made the earthquake as a potential danger. Meanwhile, since most of Iran's population live in metropolitan areas, this fact has raised the need for safer urban spaces. One of the most important urban spaces in this regard is Tabriz. The location of this city on the active faults of the region, especially the Tabriz fault, calls for the adoption of urban safety approaches. This article in terms of target is applied and the method is a descriptive - analytical one. To conduct this research, the hierarchy analysis process and Arc GIS software have been used. In this regard, 12 criteria were identified and processed in both natural and human sections and an earthquake risk map was prepared. In this regard, 12 criteria were processed in two distinct natural and human sections and an earthquake risk map was prepared. The results showed that the central, west, and southwestern regions with an area of 13969.6 hectares (more than the half city's area), 59.3 percent of the city, are in high risk of seismic zone and are quite susceptible to earthquakes. Only the northern parts of the city are secured from the earthquake; but considering the fact that the depth and domain of the earthquake are not limited to a specific area, the earthquake in the northern city may occur too. Therefore, the commitment to construction regulations, location of urban development, living spaces, and activities in this metropolis are all important factors. Manuscript profile -

Choose the wrong place causing damage to the environment, human health and pollution of surface and groundwater. Several factors affect landfill site selection and there are different ways to this issue. In this paper, GIS and analytic hierarchy process (AHP) have been used to identify suitable locations for landfill in the city of Susa. For this purpose, four main factors selected that have a substantial impact on the landfill site selection consisting of technical and operational criteria, ecological and biological, socioeconomic and physical. According to these criteria, 15 information layers prepared. The final score of the parameters were calculated by using the paired comparison. After combining 15 data layer using fuzzy analysis and AHP method and helping ARC GIS software, the final map was prepared for Solid Waste. Based on the results, western parts of the city of Susa were proposed for landfill. Because of the great distance from the city of Susa and lack of proper access road, this section has been ignored as the best place appropriate waste disposal. A closer look at the result, 3 regions, with the suitable level of value, range and access road, were determined. Manuscript profile -

One of the most important issues in rural areas, is the perfect place to dispose waste. The main purpose of this research is spatial analysis operation using GIS technology and FAHP techniques in order to locate the optimal range waste disposal of Zarrindasht city. For this purpose, in the first stage, using nine information layers which includes layers of information, distance to fault, distance from the canals, geology, soil type, distance to roads, distance from settlements, altitude, slope and land use was formed. Then, a questionnaire was designed for this purpose, and was prepared by the consultant engineers responsible for Rural Guide Plans, and finally experts of Housing Foundation of Islamic Revolution were completed that, twenty people have answered the questionnaire completely. The results show that the most optimal landfill sites were near roads and most inappropriate places were near the human settlements. The results obtained from FAHP also suggest that the measure of distance from human settlements was dedicated the most weight to themselves by a coefficient 0/232 and measure of the height was dedicated the lowest weight to themselves. The area of 4626-square-kilometer of Zarrindasht, 3.83 percent was quite suitable, 48/98 percent was suitable, 35/82 percent was fairly suitable, 9/03 percent was unsuitable and 2/33 was completely unsuitable for landfill.

The aim of this paper is to investigate the place distribution of sports land uses in Ilam City and to determine proper arenas in order to present a good pattern. The method is analytical-descriptive and the research is an applied one. The data is gathered from the libraries and by the field study and also the questionnaires and GIS maps were used. The population includes the experts of urban management and physical education in all 4 districts of Ilam City that 20 of them were chosen as the sample by Convenience Sampling and were surveyed. To analyze the data, GIS and AHP softwares were used. The findings reveal that the sports spaces are improperly distributed in Ilam City. Moreover, there has been lack of attention to the important norms and standards of sports spaces’ locating in building sports facilities. Furthermore, the views of the experts in the norms of the population density are of high importance in the norms of determining the sports spaces. In this research, 11 hectares of Ilam City’s land pieces were introduced and suggested as the best places proper for building the new sports spaces based on the determined norms and standards. .

As experts have tried to focus on the context and surroundings proximity, neighborhood, compatibility and incompatibilities, utility and other factors. By the expansion of geographical information systems, it is possible to focus on these factors and their impact on the planning process for land use allocation. At the same time, many scientific efforts have been made to integrate these systems and multi-criteria decision-making methods in order to enhance their ability to support decision making. Methods used in this field have also been widely used in various studies; one of the most important applications of these methods in urban planning is to determine the suitability of each parcel for allocating urban land uses. In this article which is applied in terms of purpose and is descriptive analytical in terms of method, the land-use suitability analysis as a scientific technique along with linear combination, and Delphi methods, have been used. Findings, which have been obtained from overlaying analytical maps (land prices, access to communication axes, number of blocks of land and air pollution's maps), indicate that what type of land use is more suitable for each parcel. The results of this paper are presented in the form of land use allocation scenarios. Comparison of the results of modeling with current situation shows that out of 2,166 parcels in the study area, 521 have no suitable uses and need change. Manuscript profile -

Forinvestigating some method in providing erosion types map at the scales1:250000 in mountainous regions, a study was conducted in Kan-Sologhanbasin, north-west Tehran, Iran. At the first stage, from integration of datalayers, four working units maps were prepared including: 1. geology, plantcover and slope, 2. geology, land use, slope, 3. rocks erodibility, land useand slope and 4. rocks erodibility, land use and land units. At the secondphase, intensities of soil erosion types in 53 ground control points werecontrolled and accurate positions were registered by GPS. Each ofworking units map was overlayed by ground control points map. Resultsindicated that maps 1, 2 and approximately map 3, are no suitable methodsfor differentiating homogenous units, because the high numbers ofworking units beside together have same erosion features. It should beregarded that the high numbers of units from an economic regards werecaused the high costs and time consuming. Map 4 including 6 units thattwo units, 66.6% and one unit, 85% of ground control points had sameerosion. In other units including agriculture lands and rocks outcrops,approximately, erosion features were uniform in all points. In general,integration of land use, rocks erodibility and land units layers is the bettermethod than other methods for providing soil erosion features map. Manuscript profile -

In this regard, construction of public parking in the vicinity of urban streets in order to avoid long and about in parks, along streets, is one of effective measures to reduce traffic. The most appropriate location for parking, where parking is most needed to be .The car park will be resolved as well. The car park will be resolved as well. Within the scope of Yazd is based on studies of traffic and transport, including 12 regional and 140 district is that a large part of the important area of the parking problem in the takes. The context for the study of the central city of Yazd is an area that overlaps with a large range of choice is an area of 765 hectares and a population of about 50,000 people. Research Methodology Type of applied research - development of; and descriptive - analytical. Studies of tissue within the central city of Yazd is, for the purpose of parking places, in addition to documents, studies, data from research that were added to the field. After collecting data - field factors were required to locate. Weight each factor from the hierarchical analysis process and then using the GIS overlay of the weight factors combined together and the final map and location of spots that were identified as suitable. Results Identifying and tracking the factors that affect the location of, the most important steps are studied. The criteria used to locate parking can be expressed as follows: 1) trip for the absorption (K): are the centers where they travel to various reasons so that it will increase traffic on surrounding streets. 2) required parking space (N): a total of 50 public parking Yazd, only 34 parking within the central tissue or in the streets of this border area is located on Park Place in 1550 only provides for the collection of stationary traffic. 3) Access to the main street (R): parking in the nearby streets to encourage more people to use them and are less confused, and accessing them is easier and faster. 4) being ruined or Bayer (M): Given the historical context of the central city of Yazd, the destruction of some of the places is not possible to construct parking places that are selected are dilapidated, and Bayer. Conclusion The results of this study are as follows: 1.locate parking in a number of factors are involved in all aspects of the analysis is not possible with traditional methods. The other hand, neglect of these factors contributed to a significant waste of material resources and the environment and serious injuries to people and urban management will be imposed. Thus the use of information technology, particularly geographic information systems to analyze large volumes of data, is essential. 2. Given the high cost of land in central and commercial area of town is best, parking will be constructed in the class because despite the poor infrastructure, large parking space and also create economic justification of accept. 3.Use of the Analytical Hierarchy Process (AHP) and Geography information system (GIS) and combined it with logic overlap index (IO) in the optimal location is a high performance site. This allows for comparing and evaluating different locations can be optimized according to specific criteria. It should be added to this landuse. 4. Use of technology to manage a city when it is realized that the spatial and descriptive data with the accuracy needed to be there. So in order to retrieve and access information quickly, forming a centralized database is essential. GIS systems are able to manage large volumes of diverse data, with the lowest possible cost, reliable forecasts of the city managers are. Manuscript profile -

The area, which contains GorganGulf and Miankale Wetland, is recorded as an international wetland in Ramsar Convention. It has high potential for tourism activities. Moreover, the increasing trend of economic development, especially oil activities in adjacent countries reveals the necessity of management and conservation of these coasts. The aim of this study is management of the coastal area by applying NOAA models and Environmental Sensitivity Index (ESI). Physical sensitivity division of coasts has been done based on field surveys and using satellite images and Geographical Information System (GIS). The assessment of physical factors including wave energy, slope and bed substance in the region under study showed that the western parts of Miankale coasts are categorized in the forth class of NOAA classification and the central part of these coasts is regarded in 9B class. Gomishan, Khajeh Nafas, Chalasht and Gorgan Gulf2 are classified as 10D according to NOAA classification. The results of this study indicated that not only physical diversity, including geomorphologic characteristics and the bed substrate of these coasts, is low but also there are sensitive biological resources in the region. For these reasons, if oil pollution occurs, pollutants may remain in coastal areas for a long time. Therefore, more attention should be paid to manage the coastal areas in this region.

It causes many irreparable damages such as soil erosion, water loss, and wealth loss. Therefore, it is important to identify the best suitable land for livestock grazing. Land suitability for livestock grazing affects by many ecosystem components but due to time and funding restrictions, the most important and feasible elements were investigated. This paper adapted the schematic model based on the concepts presented by the FAO suitability analysis for livestock grazing in Sarab Sefid Borujerd rangeland of Iran. Significant needed factors to livestock grazing such as forage; soil and water which were in sub-models were determined and incorporated into the final model of rangeland grazing suitability. Some important maps include such as: DEM, slope, aspect, range condition, range trend, forage, soil erosion, water sources used as input data. Three sub models including water accessibility, forage production and erosion sensitivity were considered. The most adaptation of Suitability occurs for class (Good) S1, (Medium) S2, (Poor) S3 and (Non-suitable) N respectively using Geographic Information Systems (GIS). First of all, the complete raster layers valued and ranked by FAO method for each factor then integrated by overlays intersected command. Results show that according to 16 types of vegetation cover there was no each of them in S1 class, 3088.75 ha S2, 1892.63 ha S3 and 882.85 ha were N class. Also result determined that there is no limitation of water resource in total rangeland and the most and main important factors effect on suitability are soil erosion and slope due to mountainous area. According to the field data and comparing with the study data it can/is possible to conclude GIS technique is fast and accurate to monitoring and determining of suit abilities of rangelands.
