| Abstract: | Objective] To estimate the function value of soil and water conservation service in order to provide scientific basis for the comprehensive control of soil and water loss and the sustainable development of soil and water conservation.Methods] Soil and water conservation function was defined, and the reference method, market value method and alternative cost method was used to estimate the service value of soil and water conservation function in Dongzhi tableland, Qingyang City of Gansu Province.Results] The total value of service function of soil and water conservation was 1.94×109 Yuan, and the value of soil and water conservation service function of land and water conservation measures was 4.32 Yuan/m2. Among them, the value of carbon sequestration and oxygen release service was the highest, amounting to 7.05×108 Yuan, followed by the functional value of improving species diversity, which was 5.34×108 Yuan, and the least was the function value to preserve soil fertility, which was 3.37×107 Yuan.Conclusion] Soil and water conservation measures in Dongzhi tableland of Qingyang City have high value of functional service. In the future, relevant water and soil conservation measures should be maintained or improved to give play to greater value of functional service. |
