        Awareness of the existence of specific weeds in an area can be better decided and planned about their control methods. Otherwise, applying different control methods will not have the desired effect. In this study, in order to identify and prepare maps of weed distribution in canola fields of Sorkhankalateh region of Gorgan county, 50 fields were selected and sampled based on W pattern in two stages. Then, using current formulas, frequency, relative frequency, species uniformity and biodiversity indices were calculated. We were recorded the geographical coordinates and altitude of the sampling location by a GPS, Garmin touch model for each field. The obtained information was processed using Arc GIS software (var. 10.3) and the distribution maps of all weeds in canola fields were prepared. The results showed that 41 weed species (20 species in the pre-spraying stage and 21 species in the post-spraying stage) from 14 plant families were present in surveyed fields of Sorkhankalateh region, which Poaceae, Asteraceae, Fabaceae, Brassicaceae and Polygonaceae were the most important plant family. In the pre-spraying stage, the share of annual, perennial and biennial species was 75, 15 and 10%, and in the post-spraying stage, their share was as 66.66, 23.80 and 9.52, respectively. In terms of growth form, in the pre- and post-spraying stages, 8 and 76.19% species were belonged to dicotyledonous and 20 and 23.80% were as monocotyledonous, respectively. According to the results of biodiversity indices, weeds in the post-spraying stage had more diversity than the pre-spraying stage. Also, the results related to weed distribution maps showed that most of the dominant weeds were distributed in the Eastern and southern parts of the studied region. Manuscript profile

        The growing trend of development and various human activities leads to the entry of various pollutants into groundwater. The desirable physical and chemical quality of water is critical to the consumer, consumer health and maintenance of the water supply system. Currently, one of the problems of underground water sources is the pollution of drinking wells and other underground resources to urban and industrial wastewater, which leads to a change in the water quality of these resources and makes it impossible for them to drink. This study investigated and zoned elements Different qualitative water flows within the city of Jajroud Basin's city by Arc GIS software. For this purpose, water quality parameters were sampled from all the sources used in drinking water in this area. Then all the information was entered into the software environment under descriptive layers and to produce qualitative zoning maps. These maps show a significant trend for most parameters, due to the widespread use of water and the probability of the outbreak of various diseases Concerned about drinking in this area, this research could pave the way for future decisions on correct water harvesting in the study area.

        As providing the quantitative and qualitative supply of safe and healthy drinking water is one of the most important responsibilities of all governmental organizations.There fors,according to the climatic conditions of our country,which is located in the semi-arid geographical part of the world,with rainfall les them 250mm and improper utilization and consumption of underground resources of water supplies in different fields in cluding agriculture,industry and social services,has brought about dramatical challenges to provide the country with healthy dirinking water.so constant bio- environmental and qualitative threats of this limited quantitative sources of water have endangered the safety and health of the people and other exploiters. so here in addition to identifying either of any environmental challenges in terms of their sources and causative organisms and its effectiveness on the health and safety of the in habitants of the villags and towns of RobotKarim , we have classified them in the forms of maps,GIS actions, ultimately providing institutional solutions to organize the challenges to minimize the deleterious effects in the future.This way we hope to provide the chances of permenant development of the target villages Manuscript profile

        Introduction   Capabilities of a database, information management and availability of data that is based on need. The purpose of this study design, data base analysis in GIS environment needs to be done. Data structure should be designed so that the logical connection between the data maintained and based on the existing data management system can be implemented. Database of economic - social Ardebil in GIS (GIS) and its data model mapping (digital or Gallery) and the raster (image or cell) in the form of database software Arc GIS version 9.3 is stored. Research Methodology The aim of the study and application of methods and descriptive nature - is analytic. Results   Gallery of data containing location and descriptive data are included in the spatial data layers of national divisions, centers, layers, units politically, the country's international borders with Azerbaijan province, the province's streams and rivers, and the height of the curves, the road layer, inner layer of the lake, the cities and digital elevation model of Earth's layers, such as video, satellite images and maps of the province is scanned. The huge volume of spatial data in vector model in the form of a geographic database (GDB) have been entered into the GIS.   * Responsible Author:                                                                  a.estelaji@iausr.ac.ir                 Conclusion   The data types stored in the system, Location and a description and analysis of reports from various databases provided then Use them to help in planning and decision-makers need to be related to possible, This article has been cited in some of them.   Manuscript profile

        With regards to the importance of soil erosion features map in watershedmanagement, and also country extent, diversity of climate, physiographic,geology, pedology, land use and plant cover, it is expectable the highdifference with due attention to soil erosion types that is caused indifferent conditions differentiate to investigate erosion features. 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
