Ecological function regionalization is a kind of geographic spatial division, which is based on the distribution of ecosystem stress and effect, ecological sensitivity and ecological service importance. The target of ecological function regionalization is to distinguish the regional ecological problems and ecological fragile areas, determine the prior protection ecosystems and regions, and to supply scientific basis for regional ecological protection, region-based ecosystem management and sustainable development. Taken Anhui Province as a case, regional ecosystem sensitivity and service importance assessment were carried out according to the established guidelines. The primary eco-environmental problems and their driving forces of study target were also extracted. With the help of GIS, the spatial distribution of ecosystem sensitivity and service importance were characterized. Based on the above assessment, the provincial ecological function regionalization was worked out, and the ecological protection and construction emphasis, target and measures of each ecological region were also recommended. It indicated that, with the stress of population and economic growth, the eco-environmental quality of Anhui Province is going worse, with the appearance of intensive utilization and lack of cultivated land, strong dependence of agricultural production on external input, resource deficit and function decline of forest ecosystem, diminution and threat of biodiversity, shrinking of wet...
