人类活动对长江河口过程的影响

Impacts of Human Activities on the Processes of Changjiang Estuary

随着经济高速发展，人类活动对长江河口过程的影响愈益显著。本文对围海造地、排污工程、取水工程、航道增深工程、南水北调和三峡工程等几项规模较大的已建和拟建工程及其对长江河口过程的影响做了初步论述，建议继续重视和加强这方面的研究，开发要适度，人工控制要遵循自然演变基本规律。

As the rapid development of national economy, it becomes more and more clear that the processes of Changjiang Estuary are being affected by the stress of human activities This paper considers some important projects such as tidal flat reclaiming, water supply, channel dredging, South-to-North water transfer and Three Gorge Project And their contributions to the processes of Changjiang Estuary are studied To assure the continuous development of this area, we suggest that the relative studies should be paid great attentions, the exploitation should be moderate, and human interference should be act according to the natural evolution rules
