Abstract: Ecological-function regionalization is the foundation of integrated management and protection of regional ecosystems, and it can provide the scientific basis for ecosystem restoration and coordination development of social economy. Based on the analysis of the main problems of ecological environment of the middle reaches oasis of Shulehe River Basin, the basis, principles and target of ecological function regionalization were determined. Using GIS and RS technology, analysis of quantitative and qualitative method, and computer graphics space iteration method, the middle reaches oasis of Shulehe River Basin were divided into 6 ecological function regions, including oasis agriculture ecological function region, Gobi desert ecological function region, wind-break and sand-fixing ecological function region, plain oasis plant ecological function region, saline controlling ecological function region and plain oasis wetland ecological function region, and 34 ecological function sub-regions. The characteristics of ecological service function, direction of ecological protection, ecological protection and restoration of ecological functions of each functional area were analyzed in the middle reaches oasis of Shulehe River Basin. The research results have certain reference function to advance smooth implementation for key management program of Dunhuang water resources reasonable utilization and ecological protection, and have important significance to advance ecological environment protection and restoration, integrated management and effective configuration of water resources and coordinated and sustainable development of regional industrial layouts and eco-economic system in arid inland oasis River Basin.
