在气候变化、经济持续高速发展的背景下，水资源形势日趋严峻。通过河湖水系连通工程改变自然水系连通情况，建立起大范围、跨流域的水资源统筹调配格局，进行水资源时间和空间上的重新分配，实现多源互补、丰枯调剂，成为解决我国水资源配置问题的新途径。相比传统水资源配置，基于河湖水系连通的水资源配置更多考虑跨流域（区域）水资源合理利用，涉及更广泛的区域范围和利益群体。基于河湖水系连通的水资源配置的基本特征和原则，本次研究提出新型水资源配置模式——权益保障与均衡发展模式，在考虑不同区域、行业、部门利益的前提下，突出权益保障与均衡发展。同时，探讨了对河湖水系连通后水资源配置中的主要技术与方法，包括跨流域水循环过程模拟技术、调水区与受水区丰枯遭遇分析方法、受水区可供水量计算方法等问题。

In the context of global climate change and rapid development of economy, the contradiction between water supply and demand was sharpening. The project of Interconnected River System Network (IRSN) can change the connectivity of nature water system to develop the large-scale and inter-basin water resources allocation framework, redistribute water resources in time and space, and then realize the multi-source complementary and high and low water adjustment, therefore IRSN strategy has become a new approach to solve the water resources allocation issue in China. Compared with the traditional water resources allocation, water resources allocation base on IRSN emphasizes the inter-basin water resources utilization, which involves a larger area and benefit group. Based on the characteristics and principle of the water resources allocation through IRSN, a new water resources allocation mode - Rights Protection and Balanced Development Mode is proposed in this paper, and the main techniques and methods of water resources allocation through IRSN are discussed, including the inter-basin water cycle simulation, analysis of synchronous-asynchronous encounter probability in the water division area and intake area, and the calculation method for available water supply in the water division area.
