Evaluating the ecological potential of the strategic sub-basin scale for territory (Case study: Chavar city, Ilam province)

It is an area of ​​science that, according to the ecological characteristics of the land and its social conditions, determines the economic and type of optimal use of the land. Meanwhile, the use of spatial data and the organization and analysis of these data is important for exploiting development issues, and has been growing at the research level of the day. Having appropriate maps of the ecological and environmental conditions of the land is very important for the evaluation. In this regard, the research studies multiple applications in a sub-field. For this purpose, the maps required after the preparation using the Arc Map software in the process Land use was integrated into Overlly's orders to evaluate the ecological capability of the ecological resource data of the basin, resulting in a map representing all the characteristics of the combined layers. In this research, based on the utilization, the priority was given to the use of semi-commercial forests with an area of ​​48.50 percent. In agriculture and rangeland, second-rate agriculture with a percentage of area of ​​34.87 percent in the lower parts of the area, including beekeeping, Horticulture included limited cultivation of low rice, such as rice, and in higher levels of sixth agriculture with an area of ​​47.02%, it indicates good conditions for rangelands, a large part of the area with an area of ​​74.02 km, In studying the results of the model at the stage of determining the power of the basin to the types of applications, the most suitable in the dock Watershed is among the most widely used forests and extensive outdoor recreation with an area of ​​37.27 and 35.42 square kilometers, which covers almost a large part of the area, and the lowest level for agricultural use with an area of ​​27.26 square kilometers According to the results of this research, the following studies can help managers in the correct management of the land and the positive productivity of the economic and social potential of the land and contribute to protecting the soil and soil that forms the basis of human life, and the ability of the land For future generations.
