Abstract: How to determine ecological compensation standard is one of the main difficulties during designing the ecological compensation scheme.Taking Danjiangkou reservoir area as a case study,ecological restoration cost and ecosystem service value of soil and water conservation in short-term was calculated.The ecological compensation standard of the exterior area was calculated based on the ecological benefit proportion which gained from the restoration project.Results show that the total soil and water conservation cost is 2.737 billion yuan(RMB) per year.The ecological service value of that brought by short-term soil and water conservation is 1.582 billion yuan(RMB),1.285 billion yuan(RMB),and 0.406 billion yuan(RMB) in restoration region,downstream region,and other related regions,respectively.According to the basic principle of ecological compensation,the exterior ecological benefited regions should compensate the cost of the restoration project,and the compensation amount of the exterior area is calculated as 1.415 billion yuan(RMB) per year.The results can provide some reference for quantitative analysis of ecological service value.Also,it can be used as theoretical foundation to carry out ecological compensation system in water source region.
