长江防洪体系与总体布局规划研究

Research on general layout planning of flood control system of Yangtze River

长江防洪体系与总体布局研究是《长江流域综合规划》的重要内容。根据长江防洪现状及长期研究与规划实践,阐述了长江中下游、上游干流及主要支流防洪体系构成及防洪对策措施;介绍了长江洪水的蓄泄关系,重点阐明了中下游防洪总体布局。指出了三峡等控制性水利水电工程建成后,以及为应对未来气候变化和适应流域经济社会发展,进一步完善长江防洪综合体系建设的必要性。

The research on the flood control system of Yangtze River and its general layout is an important content of the Comprehensive Planning of Yangtze River Basin. According to the practical condition of Yangtze River and long-time research as well as planning practice,the main components of flood control system and flood control countermeasures of the mid-lower reaches,the main stem of upper reach and the main tributaries are introduced. Under the guidance of flood control policy and principles of Yangtze River,the layout of flood control in the mid-lower reaches is taken as the keystone. The research achievements for the relationship between flood storage and flood discharge and the planned flood diversion measures for extra-flood in typical years are also presented. The necessity of perfecting the comprehensive flood control system for tackling the climatic change and adapting to the society and economy development in the basin after completion of some controlling hydropower projects such as TGP is pointed out.
