中文摘要:
      [目的]估算水土保持服务功能价值,为水土流失综合治理和促进水土保持可持续发展提供科学依据。[方法]基于水土保持功能的定义,利用参照法、市场价值法和替代成本法等方法对庆阳市董志塬区土地的水土保持服务功能价值进行估算。[结果]庆阳市董志塬区水土保持服务功能的总价值为1.94×109元,每1 m2的水土保持服务功能价值为4.3元。其中,占总服务价值最大的是固碳释氧服务价值,为7.05×108元,其次为改善物种多样性功能的价值,为5.34×108元;最小的是保存土壤肥力功能价值,为3.37×107元。[结论]庆阳市董志塬区的水土保持措施具有较高的功能服务价值,未来应继续保持或完善相关水保措施,以发挥更大的功能服务价值。
英文摘要:
      [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.
