Soil Erosion Control Values of Production and Construction Projects with Regard to Multiple Ecosystem Service Functions —A Case Study in Beijing City
[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.
