Shantou wetland is the first wetland demo-site set up by UNEP/GEF in China. Its
environmental protection is important to the wetland protection and economic
development of Shantou City, South China even the whole South China Sea area.
Accompanied by the rapid economic development and extensive urbanization, the
problem of pollution at Shantou demo-site is getting more and more severe. For the
protection purpose, the evaluation and the analysis of economic value loss in Shantou
coastal wetland caused by land-based pollution are taken out. Through the study of
land-base pollution situation from 1997-2003, it is found that the correlation between
pollution and economic value on Shantou wetland is negative. The land-based pollution
mainly affects the economic value of Shantou wetland on the aspects of wetland
productivity and state of humanity health, but the impact of the environmental amenity
degree is not so obvious. So it is suggested that the management and restoration of
wetland habitats, and controlling of pollution are very urgent. Especially the monitoring
of petroleum sewage discharge should be intensified in the future.It would be hoping
that these works will provide scientific references and suggestion on the protection and
sustainable use of this wetland.

Key Words: Shantou wetland; land-based pollution; economic evaluation
