FUZZY-SET QUALITATIVE COMPARATIVE ANALYSIS OF WETLAND GROSS ECOSYSTEM PRODUCT: THE CASE OF HUADUHU WETLAND PARK IN CHINA

With concept of ecological civilization, developing countries are trying to create systems for the quantification and monetization of ecosystem services.However, the relationships among different factors that influence the ecological product value remain unclear.To promote the development of ecological product value of wetland parks, this study takes the Huaduhu National Wetland Park in China as the study subject and conducts an evaluation based on accounting guidelines.Utilizing the alternative cost method, the ecological product values of Huaduhu Park were calculated from a temporal perspective, considering services such as water conservation, soil conservation, flood storage, carbon fixation and oxygen release, air purification, water purification, climate regulation, species conservation, leisure travel, and landscape value.Innovatively, this research applied Fuzzy-set Qualitative Comparative Analysis (fsQCA) to test the selected indices in the system.As a result, the monetary value of the ecosystem services was 122.67 million USD in 2020, and 155.71 million USD in 2023.The core factors were carbon fixation and oxygen release and air purification.The park has comprehensive ecological functions and notable cultural services compared to other regions.Thus, future research will build upon the accounting values, focusing more on dynamic wetland monitoring, modeling of biophysical processes, and related areas.
