Abstract

Eco-environmental Sensitivity assessment as a new research field on sustainable development is the foundation for establishing early warning systems for ecological safety and environmental management. Many scholars have started to study the national safety and social safety from the ecological point of view till now. Wushen Banner locates in the transitional depression between Ordos Plateau in Inner-Mongolia and Loess Plateau in the north of Shanxi Province, and in the abdomen of Mu Us Desert with a fragile environment. From the perspective of regional ecological safety, the regional Eco-environmental Sensitivity assessment index system is established including sensitivity to soil erosion, land desertification, bioinhabitation and human settlements. Based on the GRID module supported by Geographical Information System (GIS), changing the spatial data into the 30mx30m grid, through grid average weight calculation, the Eco-environmental Sensitivity assessment distribution map of Wushen Banner is compiled. This research could provide scientific basis for exploring sustainable development mode of regional resources and environment as well as guiding local development construction and ecological environment service.
