摘要：
为科学评估南水北调中线工程对河南省受水区可持续发展的支撑效能，研究聚焦河南省受水区供水情况及调水资源配置特征并量化其经济效益，基于2015至2023年中线工程供水水量数据和河南省经济社会统计资料，运用统计分析法解析中线工程河南省受水区供水情况及调水资源配置时空分布特征，核算受水区供水经济效益，构建耦合供水情况与供水效益的综合评价体系。研究表明：受水区累计获水212.61亿m3，供水结构呈现“城镇主导、农业补充”特征，城镇生活与工业供水量、引丹灌区农业灌溉供水量占比分别为61.15%和24.38%;总经济效益达2424.86亿元，城镇供水和农业灌溉贡献分别占91.3%和8.7%.量化评估证实中线工程在保障受水区经济社会发展、破解区域水资源约束、支撑新型城镇化建设方面发挥了重要作用。
To scientifically evaluate the supporting efficacy of the Middle Route of the South-to-North Water DiversionProject(SNWDP-MR) in advancing sustainable development within Henan'swater-receiving areas, this research focuses on two dimensions: the water supply dynamics and allocation mechanisms of transferred water resources in the region. Based on water supply data from the Middle Route Project from 2015 to 2023 and socio-economic statistics of Henan province, the spatiotemporal distribution characteristics of water allocation in Henan's water-receiving areas are systematically analyzed through statistical modeling, with a coupled evaluation framework being established to integrate water supply pattern analysis and economicbenefit quantification. The methodology employs industrial allocation coefficients to ensure precise accounting of water-related economic contributions. with benefit calculations covering direct outputs and ecological externalities. Research findings indicate that the water-recciving areas have received a cumulative water supply of 21261 billion m3, featuring an urban-dominated, agrieulture-supplemented allocation pattern(urban domestic/industrial water use and Yindan Canal irrigation account for 61.15%and 24.38 %, respectively), while generating total economic benefits of 242 486 billion CNY. Among these, urban water supply and agricultural irrigation contributed 91.3% and 8.7%, respectively, to the overall value creation. This empirical validation highlights the projects critical role in alleviating regional water constraints, supporting new urbanization, and securing water resources for socio-economic advancement.
