Eco-environmental problems are the main constraint factors for regional development. Regional eco-environment sensibility evaluation is important for making environmental policy and ecological construction. Based on main eco-environmental problems of Ningxia Hui Autonomous Region, soil erosion, desertification of land and soil salinization were taken as the assessment factors of eco-environment sensibility in this study. GIS technology was used for the single-factor evaluation. And on the basis, overall merit of ecological environment sensibility of Ningxia Hui Autonomous Region was gotten. The results showed that: there were four grades of eco-environment sensibility of Ningxia Hui Autonomous Region, namely insensitive, slight sensitive, moderate-sensitive and highly sensitive. Insensitive area distributed in the region of forest ecosystem, slight sensitive area distributed in loess hilly area of south Ningxia Hui Autonomous Region, low Mountain land, hills, plateaus of Yanchi and irrigation districts along the Yellow River. Moderate-sensitive area distributed in the ecological frangible zone of Ningxia Middle Arid Area and the floodplains of Helan Mountain. Highly sensitive area distributed in the fringe area of the east of Taole, the fringe area of the north of Zhongwei and serious soil desertification of Yanchi. This paper further clarified the space distribution of eco-environment sensibility of Ningxia Hui Autonomous Region, and provided the theoretic basis for policy making of environmental protection and economic development in different regions which might be of significance for regional sustainable development.
