Abstract:This study evaluated the services provided by the Shuangtai estuary wetland ecosystem in Panjin based on emergy theory. The services of the wetland ecosystem were categorized into provision, regulation and cultural supporting services. The total emergetic monetary value of the services was ¥1019.51million. Provisioning services accounted for ¥116.65million, regulating services for ¥890.65million and cultural supporting services for ¥12.21. The total emergetic value varied depending on the function of the services. The value of the habitat was highest, followed by water supply and storage, production of organic matter, regulation of atmospheric constituents, cultural research and management of pollutants. Habitat and water supply and storage accounted for 51.79% and 32.94%, respectively, of the total emergetic value. The results of this research provide a useful reference for recommendations for the protection of the Shuangtai estuary wetland ecosystem.
