黄河以北地区东线引江问题的探讨

SOME PROBLEMS REGARDING WATER DIVERSION FROM THE CHANGJIANG TO THE HAI RIVER PLAIN

南水北调东线一期工程1990年完成后,长江之水将被引至黄河南岸的东平湖,设计入东平湖的流量为50立方米/秒。第一期工程完成后,要不要扩大调水规模,把江水北送过黄河?江水调过黄河以后环境后效如何?引江穿黄与黄河水沙资源利用的关系如何?这些问题关系到南水北调东线第二期工程的规划与最终调水的规模,本文从黄河以北地区的现实情况出发,对几个有关的问题进行了分析。

This paper mainly deals with the eastern route water transfer from the Changjiang to the Hai-River-Plain north of the Huang-He.The first-stage project of the east route water transfer was approved by the Chinese state Council in Mar .,1983. After the completion of this project, about 50m3/s of water discharge would be diverted to the Dongping Lake on the south bank of the Huang-He. In consideration of the second-stage project of the eastern route water transfer, the following problems are discussed in this paper.1. Water shortage in the Hai-River-Plain north of the Huang-He;2. Conjunctive use of local water in the Hai-River-Plain and imported water from the Changjiang River.3. Impacts of water transfer upon the environment in the plain north of the Huang-He;4. Rational utilization of the Huang-He’s water resources. To sum up, the authors of the present paper would like to point out that the no-rthward water transfer from the Changjiang to the plain north of the Huang-He is Ikiely to be advisable.
