摘要：

Ecological corridor is an important means to maintain the stability of watershed ecosystem and enhance the ecological sustainability of watershed. The layout of ecological corridor can reduce the harm of landscape fragmentation caused by the rapid development of cities, especially in the arid area of Loess Plateau, which is of great significance to strengthen the connectivity of ecological patches and restore the service function of ecosystem. In this paper, taking Sanshui River Basin in Xunyi as the research object, from the perspectives of production, life and ecology, based on the landscape ecology research paradigm of "patch-corridor-matrix", the ecological source is determined, the ecological corridor is identified and constructed by the method of overlapping ecosystem services and ecological sensitivity, and finally the spatial structure of ecological corridor network in Sanshui River Basin is obtained. The results show that 65 core ecological patches can be selected as key ecological sources in Sanshui River Basin. It is identified that 75 ecological corridors form an ecological corridor layout mode of "green corridors are coherent and loops are interconnected"; According to the layout of ecological corridor, the spatial structure of ecological corridor network can be formed as "one heart, one vertical and three horizontal". The research can improve the ecological stability of Sanshui River Basin, promote the construction of ecological civilization in Sanshui River Basin, and provide scientific basis for the optimization of rural ecological space in small watershed scale.
