Evaluation of Ecosystem Service Function Value of Huangpi Lake Wetland in Anhui Province
On the basis of the research on the value of ecosystem services at home and abroad,the study evaluates the ecosystem value of Huangpi lake wetland in Anhui province by using the market value method,the results reference method,the carbon tax method,the afforestation cost method,the shadow engineering method and other calculation methods.Based on the characteristics of wetland ecosystem services,an ecological value evaluation system was established for the Huangpi lake wetland,which was divided into four first-level types:supply service value,regulation service value,cultural service value,and support service value,and eight second-level types,such as material production,water supply,and atmospheric regulation,to calculate its ecological service value.The results show that the total value of ecosystem services in Huangpi Lake wetland is 668.037 2 million yuan,of which the value of regulation services is the highest(449.149 4 million yuan),accounting for 67.23%of the total value,followed by the value of cultural services(98.149 3 million yuan),accounting for 14.69%,the value of supply services(82.976 7 million yuan),accounting for 12.42%,and the value of support services(37.761 8 million yuan),accounting for 5.65%.Its secondary types,ranked from the highest to lowest in value,are:flood regulation and storage>purification of water quality>leisure and recreation>water supply>biological habitats>material production>carbon sequestration and oxygen release,and>scientific research and education.
