As an important means to promote the territorial spatial planning system, the control of rural ecological space at watershed scale is of great significance for rural revitalization aimed at sustainable development and ecological environmental protection. Taking Sanshui River Basin in Xunyi as the research area, the paper applies the redline zoning method which integrates ecological sensitivity with ecosystem service, and collects remote sensing image data, DEM data, soil data, and also ecological environment characteristics and human activity intensity factors for a comprehensive analysis on the ecological function zone, ecological corridor and rural settlement in the river basin. The ultimate objective of the research is to propose a rural ecological space control system centered around “regionalization-network-stationing”. As suggested by the research results, in Sanshui River Basin, the area of suitable development zone, ecological control buffer zone, and ecological conservation zone is 467.35 km2, 538.86 km2 and 317.34 km2, accounting for 35.31%, 40.74% and 23.95% of the basin respectively; a basin rural ecological corridor network structure featuring “one core, one vertical line and three horizontal lines” has been constituted; approximately 387 villages are based in suitable construction development zone, 169 in ecological control buffer zone, and 82 in ecological conservation zone. The research is expected to provide scientific evidence for sustainable rural development and rational use of ecological environmental resources in Sanshui River Basin, afford specific technical support to territorial spatial planning, and reinforce space control scientificity and practicability.
