航道疏浚对珠江口附近海洋生态环境影响及预防措施

广州港航道疏浚工程中开挖和处理底泥会产生大量悬浮物，悬浮物及其含有的各种污染物将影响珠江口近海洋生态和渔业。本文主要介绍污染情况以及预防措施。通过扩散实验认为与航道疏浚工程有一定的污染，但是影响不大。通过施工前及施工期间监测结果相对照，认为航道疏浚工程对珠江口附近海洋生态环境基本没有产生大的影响，疏浚工程所采取的环保措施是极为有效的。

Influence of dredging and deepening of the outward channel on ocean ec ology and environment in the vicinity of the Pearl River Mouth and the prevetative measures

A great amout of suspended matter will be produced during dredging and deepening engineering of the Guangzhou Harbor channel. The suspended matter and the various pollutant contents will affect the ocean ecology and fishery at the Pearl River Mouth. This article mainly presents the pollutant situation and the preventative measures. It is believed through the diffusion tests that the channel but t he influence is not very big. The results of the monitoring taken before and during the engineering prove that the execution of the engineering basically has no influence on the ecology and environment in the vicinity of the Pearl River Mouth. And the environmental protection measures taken for the dredging and deepening engineering are very effective as proven by the results of location suspended matter.
