摘　　要：以崇明岛重要原水工程东风西沙水库为研究对象,基于PSR模型建立风险源、风险受体及风险响应的溢油风险指标体系,压力层选取访问概率、泄漏总量、油品种类3个指标,状态层选取库内水量可供水天数、泵闸联动补水时间2个指标,响应层选取应急预案应对能力、应急响应时间2个指标,运用AHP法确定不同指标的权重,划分溢油事故风险等级,为崇明县正常供水及水库风险防范提供依据。Dongfengxisha reservoir, the important water source project in Chongming Island, is taken as the study case. An oil spill risk indicator system containing risk source, risk receptor and risk response is established based on PSR model. Pressure layer selects 3 indicators of access probability, total leakage and oil types. State level selects 2 indicators of water supply days and water replenishment time. Response layer selects 2indicators of ability to respond to emergency plans and emergency response time. By applying AHP model, the weights of different indicators are determined and sudden oil spill risk levels are discriminated, to provide the reference for daily water supply on Chongming Island and risk prevention for the Dongfengxisha reservoir.
