Abstract

On the basis of primary data from field surveys and literature analysis, and through market value, replacement cost and contingent value methods the 2010 ecosystem service value (ESV) of wetlands in the National Wetland Parks was calculated as approximately US $20 000 ha-1 yr-1. The construction of the National Wetland Park has increased the ESV of the parks wetlands. The indirect utilitarian value is approximately 90.8%, direct utilitarian value 3.8% and intrinsic value 5.4%. The wetland park plays a critical role in increasing the local residents income and improving their living conditions.
