    Abstract:

    [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.
