长江水沙变化模式初探

Preliminary analysis of flow and sediment variation mode of the Yangtze river

长江流域水沙资源丰富,在我国社会经济可持续发展中占有极其重要的战略地位。通过对长江干、支流主要控制水文站点近50多年水文资料的搜集、整理,对长江水沙变化的过程、特点和趋势进行了介绍,并初步分析探讨了长江近年水沙变化的规律、模式。分析研究表明,长江水沙变化呈现出一定的规律性,相关研究工作应继续深入开展。

For the rich water and sediment resources, the Yangtze river is of great importance in sustainable development of Chinese economy and society. According to collected and processed hydrologic data of main hydrologic stations for nearly 50 years, the flow and sediment variation process, characteristics and tendency of the Yangtze river are introduced, and the variation law and mode of flow and sediment of the Yangtze river in near years are analyzed. The analysis results demonstrate that the flow and sediment variation of the Yangtze river has some regularity and correlative research should be strengthened.
