The static calculation of ecological service value is the main basis for determining the value of water ecological service function in a river basin. The reasonable ecological service value calculation is the premise to determine the limit value of ecological compensation standard. Based on the types and calculation methods of watershed water ecological service value, on the basis of comprehensive comparison of the applicable scope and reliability of calculation results of various calculation methods, combined with the landscape characteristics of the study area, the ecological value assessment method of watershed forest system was given. Taking the Shanxi reservoir area in the Feiyun River basin as an example, the ecological value of the four service functions of supply, regulation, culture and support services was calculated, and the total ecological service value of the reservoir area was determined to be 7.062 billion yuan/a. The ecological services value of the forest in Shanxi reservoir area in terms of water retention, environmental purification, and reduction of soil waste requires cost inputs from the people upstream of the reservoir area. In order to achieve the overall equitable, coordinated and sustainable development of the basin, the beneficiaries of the downstream ecological service value of the basin should compensate the upstream 1.498 billion yuan/a, which is about 21% of the ecological service value.
