摘要：As an important coal-resource based city in eastern China,coal mining activities have greatly promoted economic development to Xuzhou while resulted in kinds of blocks for sustainable development.Subsidence areas caused by coal mining activities and rapid urbanization process led to the losing of ecological function and decreasing of landscape connectivity in the city.As the important life-support system,urban green infrastructure (GI as short) has great significance in improving human well-beings.Taking Xuzhou urban area as the study object,this paper proposed a green infrastructure construction method based on the principle of ecological priority.Firstly,key ecological patches were identified by GIS and RS methods.Secondly,we established corridors by minimum cost path model.Then,we built GI network and evaluated the ecological importance of different patches.Finally,by comparing the status of patches and coal mining subsidence areas,we proposed a framework for constructing GI network in Xuzhou urban area.
