摘　　要：为探索公益性水利工程经济评价的重点与方法,在“23·7”海河流域特大洪水发生后,北京市各区加快重点水利工程建设、进一步完善防洪工程体系的大背景下,基于公益性工程经济属性的分析研究,系统提出了以公益性为主的水利建设项目经济评价整体框架、主要内容、量化方法、重点难点和评价目标。以北京市昌平区重点水利项目——钻子岭水库为例,进行了国民经济评价的实例计算,结果表明:项目经济内部收益率EEIRR、经济净现值EENPV、经济效益费用比RBC均大于限值,当敏感因素向不利方向浮动时,指标仍在合理范围内,说明项目在经济上是合理的,经济评价内容、方法,可为同类型建设项目提供参考。To explore the key aspects and methods of economic evaluation for public water conservancy projects,this study examined the context in Beijing'districts where the construction of key water conservancy projects and the flood control system were accelerated following the"23·7"catastrophic flood in the Haihe River Basin.Based on an analysis of the economic attributes of public projects,a comprehensive framework was systematically proposed for the economic evaluation of water conservancy projects with a public focus.This included the overall framework,main content,quantitative methods,key challenges,and evaluation objectives.Using the Zuanziling Reservoir,a key water conservancy project in Changping District,Beijing,as a case study,a national economic evaluation was conducted.The results showed that the project's economic internal rate of return E_(EIRR),economic net present value E_(ENPV),and benefit-cost ratio R_(BC)all exceeded the threshold values.Evenwhen sensitive factors fluctuate in an unfavorable direction,the indicators remained within a reasonable range,indicating that the project is economically viable.This study provides a reference basis for the application of evaluation on the similar projects.
