Abstract：How much the value that the human being gets from the soil and water conservation measures? This problem can be solved by estimating their ecological services.It can measure the ecological service by economic ways in given scale or area based on the theories of bio-ecology and ecologic-economics.The ecological services values included such as conserving water resource,preventing soil losses,sequestrating carbon & concentrating oxygen,cleaning air,fixation sand land,and protecting biodiversity.Using the market value method,shadow engineering technique,production cost method,and opportunity cost method,the total values of ecological services offered by soil and water conservation measures had been put forward.The results show that,in 2004,the total value of newly added soil and water loss comprehensive control measures is 211.78 billion yan,it includes as such,conserving water resource value is 40.6 billion yan,preventing soil losses value is 88.99 billion yan,sequestrating carbon &concentrating oxygen value is 10.69 billion yan,cleaning air value is 18.32 billion yan,combating sand value is 17.20 billion yan and protecting biodiversity value is 35.98 billion yan. Furthermore,the values of conserving water resource and fixation sand land were very extrusive.
