GIS-based study on the partition of different ecological-functional areas and development strategies of Jinchang City

Ecological-functional regionalization is the basis of regional ecological protection, scientific management, and sustainable utilization of natural resources. In this study, data of soil erosion sensitivity and significance of water conservation were analyzed based on ArcGIS in order to partition different ecological-functional areas of Jinchang City. Five zones were partitioned: Ⅰ, forest-grass water conservation ecological barrier area in the southwestern mountain area; Ⅱ, circular economy ecological development area in the corridor; Ⅲ, xerophytic vegetation restoration area in the shallow hills and hills in the central part; Ⅳ ecological construction area in the northern Gobi area; Ⅴ, ecological protection area in the northern Gobi area. According to the characteristics of each area, the corresponding development measures were proposed, which may provide a theoretical basis for the eco-environment protection and the delimitation of the ecological red line.
