河口疏浚对环境的影响

Influence of Estuarine Dredging on Environment

论述了河口疏浚对环境造成的影响。疏浚利于排涝泄洪,利于通航,在挖除含有污染物质的淤泥后,还可消除污染危害;同时也会产生许多不利影响,包括局部水域浑浊、盐水楔上溯、生态环境的改变等。然后对如何采取措施减少疏浚引起的负面影响,特别是针对疏浚弃土的处理,最大限度地发挥其利用价值,进行了初步探讨。

This paper describes the influence of estuarine dredging upon environment Dredging mainly benefits the flood control and navigation, as well as the environment protection after removing the polluted material, meanwhile it may also cause lots of disadvantageous influence, including suspension of bed silt, salt wedge ascending, change of partial ecological environment, etc. And the measures to reduce the negative influence induced by dredging are briefly introduced and probed into, especially the treatment and application of the dredged material.
