摘要

Wetlands provide many important services to human society, but are at the same time ecologically sensi-tive and adaptive systems, and are under heavy pressure. As a wetland city, Shanghai city has various types of naturalwetlands (chiefly, includes coastal, riverine, laustrne， and reservoir and pond wetlands)，which account for 23.5% of total areas. Meanwhile, Shanghai is a metropolitan city, being confronted with the pressure of port expansion and ur-ban and industrial sprawl,just like the other megalopolises in the world. Based on our earlier study on estimating the ec-ological service values of wetlands in Shanghai, this paper analyzed the ecological functions of the wetland city, such asnutrient cycling, water regulation and supply, food supply，disturbance control, water treatment, habitats and refugia,aesthetic, education and culture, tidal flats and potential land resources. Unfortunately, the wetland function was beingdegraded and the ecosystem service was discounted accordingly because of over-reclamation, over - fishing, water pol-lution, and rapid urbanization in the city.It's therefore recommended that,to improve the environment of Shannghai ciry，and make the ecosystems sustainable function appropriately, the effective wetland management strategies should be taken.
