| 为提升长江黄河跨流域水网的整体运行效益，针对南水北调东、中线管理实践需求，以调水满足率最大、公平性最佳，及受水区社会、经济、生态效益最大为优化目标，构建成网互济运行方式下“源-流-网-配”协同优化模型。基于长江、黄河枯水、特枯水组合的4种情景，对比分析单线运行与成网互济运行方式，分析其有效性。结果表明：长江枯水变化对受水区缺水率影响较小，黄河枯水变化下山东缺水率变化更大，同时黄河丰枯变化会影响成网互济的效果；相较于水网单线运行，成网互济时受水区总缺水量降低4.2~13.3亿m3，河南、山东黄河受水区缺水率下降0.1%~6.7%，南水北调、非常规水供水量上升，地下水和黄河水减少7.7亿m3，改善了部分地区供水结构；互济调配下南水北调东、中线可调减引黄用水指标分别为12.7亿m3、11.1亿m3，是基准方案中原调减指标的3~6倍。研究成果可为水网科学调配提供决策参考。 |

| In order to improve the overall operational efficiency of the inter-basin water networks of the Yangtze River and the Yellow River, this paper conducted a study on the practical requirements for the management of the eastern and central routes of the South-to-North Water Diversion. With the optimization objectives of maximizing transferred water satisfaction rate, optimizing equity, and maximizing social, economic and ecological benefits of the receiving areas, the study constructed a synergistic optimization model of “source-flow-network-distribution” under the operation mode of forming a network and mutual aid. Based on four scenarios of the Yangtze River and Yellow River with dry water and especially dry water, the model compared and analyzed the single-line operation and the network mutual aid operation. The results show that: Changes in the Yangtze River withered water have less impact on the water shortage rate of the receiving area, and changes in the Yellow River withered water have more changes in Shandong's water shortage rate, while changes in the Yellow River's abundance and desiccation affect the effect of forming a network of mutual aid; compared with the single-line operation of the network, the total water shortage of the receiving area is reduced by 0.42 to 1.33 billion m3 in the case of forming a network of mutual aid, and the shortage rate of the receiving area of the Yellow River in Henan and Shandong is reduced by 0.1% to 6.7%, and the amount of water supply of the South-to-North water diversion, unconventional water Water supply rises, groundwater and Yellow River water decreases by 0.77 billion m3, improving the water supply structure in some areas; under the reciprocal allocation of the South-to-North Water Diversion East and Central Lines, the indicators of water diversion from the Yellow River can be adjusted down to 1.27 billion m3 and 1.11 billion m3 respectively, which is 3-6 times of the original reduction indicators in the baseline scenario. The research results can provide decision-making reference for the scientific deployment of water network. |
