中文摘要：
以前的研究证明在 Datong 在在 Yangtze 河口和分泌物的盐水的侵入之间有强壮的关联。在不久的将来，长江的分泌物将由于大水转向工程的构造和操作在旱季期间减少，包括 South-to-North 水转移工程，它将进一步在河口加重盐水的侵入。在这篇论文，一个嵌套的 1D 河网络模型和 2D，盐水的数字模型被用来在 Datong 在 Yangtze 河口把盐水的侵入与分泌物的不同价值联系。13 000 m 3/s 是在为阻止盐水的侵入并且控制 South-to-North 水转移工程转移的水的体积的 Datong 的批评分泌物，这被结束。而且，基于到 Xuliujing 并且在水的所有的影响的考虑的从 Datong 的河分泌物的分析，转向投射，操作计划为 South-to-North 水转移工程的东方线路被建议不同水文学年。
英文摘要：
Previous research shows that there is a strong correlation between saltwater intrusion in the Yangtze Estuary and discharge at Datong. In the near future, the discharge of the Yangtze River during dry seasons will decrease due to the construction and operation of large water diversion projects, including the South-to-North Water Transfer Project, which will further exacerbate saltwater intrusion in the estuary. In this paper, a nested 1D river network model and a 2D saltwater numerical model are used to associate saltwater intrusion in the Yangtze Estuary with different values of discharge at Datong. It is concluded that 13 000 m3/s is the critical discharge at Datong for preventing saltwater intrusion and controlling the volume of water transferred by the South-to-North Water Transfer Project. Furthermore, based on the analysis of river discharge from Datong to Xuliujing and in consideration of the influence of all of the water diversion projects, operation schemes are proposed for the Eastern Route of the South-to-North Water Transfer Project for different hydrological years.
