英文摘要	With population growth and economic development, urban ecosystems are facing serious ecological risks from multiple pressures. Through a case study of the Shenzhen River-Bay watershed, which had experienced rapid urbanization, a Pressure-Effect-Social Response (PESR) ecological risk assessment indicator system was established based on the Pressure-State-Response (PSR) framework. Risk index for each sub-ecosystem was calculated through Fuzzy Comprehensive Evaluation (FCE). The risk grading and the potential ecological risk for the Shenzhen River-Bay watershed were determined. The results showed that the ecological risk of the Shenzhen River and the Shenzhen Bay watershed remained at high and medium levels from years 2001 to 2005, respectively. Appropriate measures should be implemented to mitigate the ecological risks in this area. The results provide a scientific basis for risk prevention management in the study area and can be of reference for other urbanized areas.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000291492300006&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Biodiversity Conservation; Environmental Sciences; SCI(E); CPCI-S(ISTP); SSCI; 2
