Based on the management principle and objective of Jiangsu SNWDP, the thesis establishes its management framework and designs three management patterns and four modes. Through analyzing the anticipative management effect, scopes in point, advantages and disadvantages of each modes seriatim, the thesis confirms the recommended pattern. It makes framework refinement design, defines rights and duties of control level, execution level and participation level for the recommended pattern. According to the principles of planned water use, metered water use, contract water use, toll water use, it studies project operation for recommended pattern from four aspects, namely water supply plan, measure intensified, water supply contract, and water rate enacted. The thesis analyses and studies how to ensure water supply quality of Jiangsu SNWDP from three levels, including doing watershed protection, intensifying intermediate process, and establishing a long-term mechanism. It makes brief design for dispatching management applied system, studies emphases parts which may affect operation of the pattern in practice, also analyses dispatching optimization of Provincial boundary project management, pumping station management, and different water resources. Finally, the thesis studies relevant basal supports and development stratagems for the management of Jiangsu SNWDP.

本文从分析南水北调江苏境内工程的管理原则、管理目标入手，构建南水北调东线江苏境内工程管理组织框架，设计了管理的三种模式，四个方案，对各种方案的预期管理效果、方案的适用范围、方案的利弊逐一分析，经比选后确定推荐模式；并对推荐模式进行结构细化设计，界定调控层次、执行层次、参与层次的权责；从供水计划、加强计量、供水合同、水价制定方面对推荐模式进行了工程运营的具体研究；从做好源头保护、强化中间过程、建立长效机制三个层次，分析研究如何确保南水北调江苏境内供水水质；对调度管理应用系统作了简要设计；针对实际管理中可能影响整个模式运行的重点细部：省界工程管理、泵站工程管理、不同水资源的优化调度等进行了研究；本论文还分析研究了南水北调江苏境内工程管理的相关基础支撑和发展战略。
