The urban wetland plays an important role in the urban ecosystem,which has functions that cannot be replicated by other ecosystems.It is crucial to assess the wetland ecosystem service value(WESV).Existing research on the WESV gives lit-tle consideration to the impact of urbanized areas on wetland ecosystem.To improve the estimation of the service value of urban wetland ecosystem,a water yield factor is introduced,based on the method of modifying the equivalence factor table by the spa-tial and temporal regulation of precipitation.The WESV of t...
