长江中下游河道岸线的整治与开发利用

通过分析长江中下游河道的各段的整治措施，提出长江中下游河道整治的关键是：（1）控制河势，治理河岸崩塌，增强河床与河岸的稳定性；（2）充分重视三峡工程建成后对河道变化产生的影响；（3）科学合理地控制好长江采砂。并分析了长江岸线开发利用现状及存在问题，提出了岸线利用的原则。在长江中下游河道岸线利用过程中，还存在：河势不稳定，布局不合理，深水浅用浪费岸线资源和水污染严重等问题，提出遵照河道演变规律开发岸线，保护河岸工程的安全，根据河岸水质污污染与河床特点合理布置引水口和排污口，提高引水质量。

Governing and Exploiting the Water Front Resources at Middle and Lower Reaches of the Yangtze River

The article adequately analyze the governing measures on every section of the middle and lower reaches of the Yangtze River, and a series of key ways to maintain and harness the river course at the middle and lower reaches of the Yangtze River were put forward, namely, 1) control the river situation, harness the collapse of river bank, strengthen the stability of river bed and bank. ; 2)pay full attention to the possible influences on river course change which caused by 'Three Gorges Project' ; 3)regulate the sand-mining in the Yangtze River scientifically and rationally. In addition the current situation and existing problems of exploiting on the water front resources of the Yangtze River was also analyzed, according to it, the principles of exploiting the water front was proposed. In the process of exploiting the water front resources at the middle and lower reaches of the Yangtze River, some problems also exist, such as instability of river situation, irriational distribution, serious water pollution and the waste of water front resources. Further solution must be worked out.
