The value assessment of ecosystem service function in Lingang Wetland Park

摘要

In this study, the ecosystem service function value of Lingang wetland park was calculated, such as hydrological regulation, water conservation and purification, biological habitat, erosion control, carbon sequestration and oxygen release port, with the market value method, carbon tax and forestation cost method, shadow engineering method, replacement cost method, ecological value method and other methods. The results showed that the total ecosystem service function value of this wetland park is ￥1.03×10~8·a~(-1). The species habitat, carbon sequestration and oxygen release and hydrological adjusting function value is larger, which is 40.3%, 38.3% and 13.0% of the total value, so they are the main core function value of the Park. Therefore, the scientific and rational planning should be carried out in the development of the wetland park, avoiding influencing the ecosystem service function of this park.
