继前一部分对20世纪90年代以来长江上游河川径流与输沙量变化及其对长江水资源形势和水利工程的影响进行了初步研究和讨论,对未来长江上游重要的大型水资源工程的宏观影响和作用进行了初步研究。本文结合长江流域和跨流域调水增加用水的需要和气候变化可能对长江水资源带来的不利影响,本着开源节流、有效管理与合理布局的思路,对长江上游水资源工程建设、管理及相关问题提出了一些初步的看法与建议:①加快推进上游干支流控制性水资源工程建设;②对上游大型水资源工程统一管理和整体优化调度;③研究比当前南水北调西线工程更合理的线路布局;④全面治理洞庭湖,控制荆江河道出现的大幅度冲刷。
Following the previous part of the Yangtze River upstream since the 1990s, runoff and sediment load changes in the Yangtze River and its impact on water resources and water conservancy projects conducted a preliminary study and discussion on the future of the upper reaches of the Yangtze River important macro-impact of water projects And the role of a preliminary study. Based on the needs of water diversion in the Yangtze River Basin and inter-basin watershed and the possible adverse impacts of climate change on the water resources of the Yangtze River, in line with the ideas of increasing income and reducing expenditure, effective management and rational distribution, the construction, management and correlation of water resources in the upper reaches of the Yangtze River Some preliminary opinions and suggestions are put forward: (1) accelerating the construction of controlled water resources in upstream and downstream tributaries; (2) unified management and overall optimization of large-scale water resources projects; (3) more rational route layout than the current project ; ④To completely control Dongting Lake and control the drastic erosion of Jingjiang River.
