摘要

According to the characteristics of wetland resources in Xinghu National Wetland Park and combined with the ＂Wetland Ecosystem Service Assessment Specification＂, this paper selects 11 ecological service functions, compares the ecological service value of wetlands per unit area of wetlands in Zhejiang Xianshan Lake Wetland Park and Yellow River Delta Nature Reserve, and evaluates them by shadow engineering method, equivalent factor method, tourism cost method and other calculation methods. The results showed that the total value of ecosystem services in Xinghu National Wetland Park was 29.17567 million yuan, of which the material production value was 19.62282 million yuan, accounting for 67.2575% of the total service value. Secondly, the value of water purification and carbon sequestration and oxygen release was 27.6248 million yuan and 27.0061 million yuan, respectively, accounting for 9.4684% and 9.2564% of the total service value. The value of ecological function services per unit area of Xinghu Wetland is 311,900 yuan/ha, which is significantly higher than that of 83,600 yuan/ha per unit area of Xianshan Lake Wetland, and the value of wetland service per unit area of Xinghu National Wetland Park is significantly higher than that of wetlands in the Yellow River Delta Nature Reserve.
