摘　　要：娄里水库是洺河流域防洪体系的重要工程,主要任务为防洪,主要防洪保护对象为坝址下游的永年城区、洺河两岸村镇和耕地、大陆泽宁晋泊缓滞洪区。分析了娄里水库防洪效益,其中永年城区防洪效益采用最优等效替代法,其他地区直接防洪效益采用频率法进行计算,适当考虑间接防洪效益,在防洪效益分析的基础上进行经济评价。结果表明,娄里水库防洪效益显著,经济内部收益率等指标符合规范要求,经济可行。未来进行防洪效益分析时,还应充分考虑人民生命、生态和社会等非经济效益,完善现有防洪效益的分析计算方法。Louli Reservoir is an important project in the flood control system of the Minghe River Basin.Its main task is flood control,and the main flood protection objects are Yongnian District downstream of the dam site,villages and farmlands on both sides of the Minghe River,and Ningjinpo detention basin.The flood control benefit of Louli reservoir was analyzed.The flood control benefit of Yongnian city was calculated by using the optimal equivalent substitution method.The optimal equivalent substitution method was used in Yongnian District.In other areas,the frequency method was used for calculation,the indirect flood control benefit was properly considered,and the economic evaluation was carried out on the basis of the flood control benefit analysis.The results showed that the flood control benefit of Louli Reservoir was remarkable,the indicators,such as economic internal rate of return,met the standard requirements and were economically feasible.In the future,non-economic benefits such as people's life,ecology and society should be fully considered in the analysis of flood control benefits,and the existing analysis and calculation methods should be improved.
