摘　　要：研究南水北调东线一期工程通水以来受水区生态环境效益的演变态势,对南水北调后续工程高质量建设、加快构建国家水网以及促进工程综合效益发挥有决策参考作用。以定性定量相结合的方式分析东线一期工程在优化水资源配置、保障饮水安全、复苏河湖生态环境和畅通南北经济循环等方面的作用,进而结合层次分析法,从直接效益和间接效益2个方面,筛选构建东线一期工程受水区生态环境效益评价指标体系,主要包括工程年供水量、水质改善度、生态补水量、地下水压采量、地下水水位、水域面积、绿地面积和涵养水源等,并采用VlseKriterijumska Optimizacija I Kompromisno Resenje(VIKOR)多准则妥协解排序方法对南水北调东线一期工程通水以来即2013-2022年受水区生态环境效益演变态势进行分析。结果表明:南水北调东线一期工程通水的10年以来,受水区的生态环境整体复苏效果明显,近3年排序值保持在0.8以上;受降水偏枯进而影响地下水开采量和地下水水位等因素影响,2019年间接生态环境效益下降29.2%,之后迅速恢复并保持稳定。在分析直接效益和间接效益演变的基础上,从工程提质增效、提高工程水质状况以及完善体制机制建设等方面提出东线一期工程进一步促进受水区生态环境持续改善的策略和建议,以期为东线工程及受水区生态环境保护及高质量发展相关研究、决策制定等提供参考。The phase I of the Eastern Route of the South-to-North Water Transfers Project(hereinafter referred to as Phase I)is an important part of the South-to-North Water Transfers Project and the backbone project of the national water network.Under the background of the current ecological civilization construction,the eco-environmental benefits of the receiving area of the project are widely concerned.Phase I has been in operation for nearly 10 years.As of the end of June 2023,a total of 6.139 billion m^(3) of water has been transferred to Shandong,which has brought remarkable benefits.So,scientific analysis of the eco-environmental evolution of phase I is conducive to the highquality promotion of subsequent projects and the high-quality development of economy and society.To analyze the evolution characteristics of eco-environmental of the phase I,the role of phase I is analyzed in optimizing water resources allocation,ensuring drinking water safety for the masses,reviving the eco-environment of rivers and lakes,and smoothing the North-South economic cycle by combining qualitative and quantitative methods.The indicators,such as annual water supply,water quality improvement,ecological replenishment,groundwater pressure recovery,groundwater level,water area,green area,water conservation,were selected,and the eco-environmental benefit evaluation indicator system of the phase I was established.On this basis,the ecoenvironmental evolution analysis method of the phase I was established based on VIKOR compromise solution ranking method,considering the incongruity between multiple indicators.The constructed evaluation indicator system and evolution analysis method are applied to calculate and analyze the evolution situation of eco-environmental benefits of the phase I from 2013 to 2022.The results show that:The overall benefits have been gradually increasing since the opening of water supply,reaching a peak in 2020,and then basically stabilizing.The phase I has promoted the recovery of underground water pressure,water level,the
