Abstract	In order to effectively study the regional soil and water ecological environment and its ecological restoration in China’s key ecological protection regions. This paper discusses the ecological problems of soil and water resources from the two research fields of vegetation degradation and soil erosion, and analyzes the causes and effects of ecological restoration measures in recent years. Then, the collected data and the SWAT model were used to study the ecological restoration performance of water and soil resources and the coupling degree of land resource utilization rate and water and soil resources from four aspects, respectively water resource quantity, water resource development utilization rate, land resource utilization rate and coupling degree of water and soil resources. This paper analyzes the coordinated relationship between regional economic development and ecological environment through coupling analysis method, evaluates the level of regional coordinated development at the same time, and puts forward the coupling index of regional coordinated development between regional economy and ecological environment. From 2009 to 2019, the index in Tianshui, Longnan, Baoji and Hanzhong showed a trend of first increasing, then decreasing and then increasing.
