[目的] 探讨现有土壤流失控制值确定方法能否满足多元的现实需求,尝试提出可以维护多重生态服务功能的生产建设项目土壤流失控制值确定方法,为进一步细化控制值的制定提供科学支持。[方法] 以北京市为例,选择易获取的容许土壤流失量和背景土壤侵蚀模数作为依据制定土壤流失控制值,分析它们在不同区域维护生态服务功能的优缺点,提出一个可以维护多重生态服务功能的生产建设项目土壤流失控制值确定方法。[结果] 基于容许土壤流失量确定的土壤流失控制值,在山区可以同时满足维护供给和文化服务功能的需求,但在平原和部分水土保持敏感区不能充分满足维护文化或调节服务的需求。基于背景土壤侵蚀模数确定的土壤流失控制值,在平原和部分水土保持敏感区能满足维护文化和调节服务功能的需求,但在山区不能满足维护供给服务功能的需求。将这两种方法结合起来确定北京市生产建设项目土壤流失控制值,能够同时满足维护山区和平原区供给和文化服务功能的需求。[结论] 维护多重生态服务功能的生产建设项目土壤流失控制值的确定方法弥补了单纯依据容许土壤流失量确定土壤流失控制值的不足,为完善生产建设项目水土流失防治目标的制定提供了新的思路。
[Objective] In order to provide scientific support for specifying soil erosion control values of production and construction projects
this study discussed whether currently used methods of defining soil erosion control were capable of satisfying multiple needs
and attempted to implement a method for defining soil erosion control values that will maintain multiple ecosystem service functions. [Methods] Taking Beijing City as an example
soil loss tolerance and background soil erosion moduli were selected
which can be easily obtained
as the references for defining the soil erosion control values
to analyze their advantages and disadvantages on maintaining regional ecosystem service functions in different areas. A method was carried out for defining soil erosion control values of production and construction projects for maintaining multiple ecosystem service functions. [Results] Soil erosion control values obtained from soil loss tolerances could keep provisioning and cultural services in mountain areas
but could not in plain and some environmentally sensitive areas. The situation was reversed when soil erosion control values obtained from background soil erosion moduli. Defining the soil erosion control values of production and construction projects by combining the mentioned two methods could keep provisioning and cultural services both in mountain and plain areas. [Conclusion] The method for defining soil erosion control values of production and construction projects
by which multiple ecosystem service functions are maintained
could overcome the disadvantages of the values defined only by soil loss tolerance. The method provides a new pathway for setting prevention and control goals for soil and water conservation.
