Therefore, identifying landscape aesthetic beauty, and also fundamental planning and valuable areas, and proper planning and design in order to protect and promote the aesthetic value seem to be necessary and unavoidable. In this research, the aim is to investigate the performance of various experimental methods (multi-criteria evaluation using weighted linear combination), mathematical (logistic regression), and intelligent (neural network)) in estimating the suitability of the aesthetic value of Gorgan city. After theoretical studies and determination of effective criteria, mapping and standardization of the criteria were done and finally, the map of aesthetic-value suitability was prepared based on the methods of weighted linear combination, neural network, and logistic regression. In order to evaluate the performance of different methods and choose the optimal method, ground control points and ROC validation methods were used. The results showed that in the map resulting from the weighted linear combination method, a large part of the data was lost as a result of the linear combination of layers and weighting, and the neural network method with intelligent performance and the ability to combine and analyze non-linearly compared to the weighted linear combination method and also performing back and forth analysis compared to the logistic regression method, better separates the value of the studied area. According to the results of this research, it can be concluded that when there is little knowledge about the studied area and it is not possible to conduct field surveys to record valuable points of view, performing the weighted linear combination method can be a solution, but if it is possible to conduct field surveys to prepare a map of real educational samples as a dependent variable, more accurate results can be obtained with the help of the neural network method and logistic regression, more accurate results can be achieved, and in the meantime, the intelligent neural network method has a higher ability to distinguish the values of the environment image.

Howe MoreBackground and Purpose: Optimal and principled use of natural resources and land use management based on ecological potential, has an important role in environmental management and prevention of environmental degradation in the direction of sustainable development. However, ignoring the social need, despite considering the economic and especially the ecological potential in land use planning, leads to inconsistency with the terrestrial reality, which is one of the basic principles of any land use planning. Materials and Methods: In this study, using weighted linear combination method and hierarchical analysis and standardization of criteria using fuzzy sets, in addition to preparing an ecological and economic potential map for agricultural use, the social needs to change land from barren lands to agriculture were also mapped. By combining all of them, a map of the desirability of changing barren lands to agriculture in the Semnan watershed was obtained, which can also be used in modeling land use changes. Results: In this study, unemployment rate and population growth rate in the next ten years as the most important social factors of agricultural land use change, access to roads and electricity as the most important economic factors, and soil and water as the most important ecological resources of agricultural land use were determined. Discussion and conclusions: Considering the social needs and economic potential along with ecological capability, is more in line with the ground reality and can be used in the optimal allocation of agricultural land.

This area is one of the nine reserves in Iran, and 66.5% of it is covered by forests. In this study, land capability evaluation of this area for forestry was carried out in Geographic Information System (GIS) surrounding. Method: Both Boolean and weighted Linear Combination (WLC) methods along with analytical Hierarchy Process (AHP) were used. First, the ecological characteristics of the study area including elevation, slope, soil texture, climate, value of vegetation type, soil depth and vegetation density were studied and then the calibrated model for forestry in Arasbaran area was created. Findings: In the first step, land capability assessment was done using Boolean method and results showed the presence of class capabilities of third, fourth, fifth, sixth and seventh, and lack of class capability of first and second for forestry. In the next step, the importance of criteria and sub-criteria was calculated using expert’s comments and AHP technique in Expert Choice 11. Then, land capability assessment was done using weighted linear combination. The results showed that all of the seven suitability classes for forestry were proper in the area. Discussion and Conclusion: Mc-Harg systemic model has been used to evaluate the ecologic capability evaluation for many years. The new process in ecologic capability evaluation is to use the mathematical models and to use the analytical hierarchy process for determining the weights and relative importance of the alternatives and for ecologic capability assessment by geographic information systems (GIS). In this study, to evaluate the forestry ecologic capability, both Boolean and WLC methods were used and the advantages and disadvantages of them were investigated. Manuscript profile -

The ecological criteria such as soil, climate, water resources, geology and physiographic, as well as socioeconomic criteria, such as land use, distance from road, distance from built-up areas, distance from sightseeing attractions, and distance from tourism facilities were identified and then quantified using fuzzy method. In order to generate a land use map, remotely sensed data of OLI land sat 8 dated was used. Field data were collected in 2015. Thereafter, the factors influencing the allocation of lands to ecotourism were ranked using analytical network process method. Finally, using a weighted linear combination (WLC) operator, all information layers were combined in a ArcGIS®10.1 environment, followed by preparation of the final map of the ecotourism development power. In order to carry out the accuracy assessment, 20% of homogeneous land units which were suitable for ecotourism were randomly selected. The result of field check proved that 94% of the identified land units were completely compatible with natural condition. The obtained results indicate that the ecological criteria account for 0.64 of the final weight in total, suggesting the greater involvement of ecological criteria in developing functionality for ecotourism. The results from the quantitative method (WLC) showed that 75.2% of the study area are capable for ecotourism purposes, although the degree of culpability is varied. The rest (24.8%) has no suitability for ecotourism. From the capable areas, about 30.32% are highly capable for different ecotourism purposes. Concomitant use of fuzzy logic and ANP method for prioritization of criteria provides a more logical and flexible condition for land evaluation based on WLC method. Manuscript profile -

Therefore, for the optimal management of the natural areas, awareness of the land use ratio is a necessity. Soil erosion is one of the environmental disasters that annihilates thousands of soil, crops each year, and land use change is one of the important factors in erosion. Therefore, the present study was conducted to investigate the land use change trend in Nair, Ardabil province, and its effect on erosion using GIS and RS in order to carry out the research, images from 2000 and 2016, OLI and TIRS sensors, Landsat 8 were used and land use map was prepared using a controlled classification method. The erosion zonation map was performed using landuse maps and factors such as slope, lithology, distance from the road, distance from the waterway, precipitation and soil using Critical Weighing and Weighted Linear Combination (WLC). The results showed that the highest amount of area in 2000 was related to dry land farming with 442.38 km2 and semi-condensing pastures with an area of 347.39 km2. In 2016, the highest area of use of rangelands density, and then the use of semi-metamorphic rangelands are 478.76 and 458.5 km2, respectively. According to the erosion zoning plan of 2000, 17.25% and 25.55%, respectively, according to the 2016 erosion zonation, 12.44% and 26.51% of the city area are located in two high risk and high risk categories. Mostly, high risk and high-risk areas are located in both dry land and aquaculture fields at both time periods. Manuscript profile -

But the wide variety of options and parameters, variables uncertainty and long terms in environmental planning, causes the decision-making becomes more complex. So multi-criteria decision-making methods can meet these challenges. Thus the aim of this study is to identify suitable areas for eco-tourism in Kiamaky wildlife refuge using MCDM method Based on fuzzy logic in GIS. According to the effective criteria on the eco-tourism in this area; obtained from previous research and expert opinions, 15 criteria maps (climate, lithology, height from sea level, slope, aspect, land use and distance maps from residential area, road, river, police station, environmental guard station, sensitive habitats, shrine, spring and waterfall) are produced and classified as input. To determine the weights of criteria, opinions of experts in the form of Delphi Method were applied. The criteria matrix formed and the relative importance of all criteria was defined using the AHP method and pairwise comparison. Finally eco-tourism appropriate priority map was produced using Weighted Linear Combination (WLC) method and applying the index of the importance of each criterion to corresponding classified map. According to mentioned map, 15% and 34% of the area eligible for perfect and good for eco-tourism respectively, and 4% of the area are medium for this purpose. In this study, besides confirming previous studies, power and usefulness of GIS in locating and combining different ecological criteria were shown. Manuscript profile -

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 -

Accordingly, identifying the capabilities of the land before loading various activities is very important. Otherwise, many of the investments will be wasted. As a result, assessing the land use potential for planting different crops is the first strategic priority for increasing production and optimizing resource consumption. In order to study the role of physiographic factors in the ecological capability of Golestan province for the planting of peas, geographic information system and weighted linear combination method were used. Agricultural needs and geological variables including soil texture, elevation, slope and aspect are determined from the available scientific resources, grading and required maps were prepared. For data standardization, fuzzy logic was used and we used the analytic hierarchy process (AHP) method to weigh the criteria. Finally, using the weighted linear combination (WLC) method in the TerrSet software environment, a potential mapping plan for peas was prepared. The results of the weighting of the criteria with the AHP method showed that the slope with the maximum of 0.2790 and the elevation had the lowest coefficients of 0.1038. Also, the results showed that a large part of the agricultural lands located in the province center (70.51%) has suitable conditions for the planting of peas and 6.08% of the total area of land is less suitable and 7.2% is half suitable, which includes lands Located in the mountainous and highlands of the province.
