湖泊富营养化的生态修复策略

Approach for ecological restoration of lake eutrophication

由于工业化的发展和人类生产活动的加剧,大量有机污染物不断排入湖泊并在其中积累,致使湖泊产生了富营养化现象,当前我国湖泊污染及富营养化问题非常严重。文中论述了湖泊富营养化的现状及危害,分析了产生的原因,指出生态修复是治理的最佳途径。因此,湖泊治理应该遵循先控源截污、后生态恢复,即先改善基础环境,后实施生态恢复的战略路线。

As the development of industrialization, the growing human production activities, a lot of organic pollutants were discharged into lakes and in which accumulated, which causes the lake eutrophication. Lake pollution and eutrophication have become an important issue in China. This paper described the status of eutrophication of the lakes and hazards, analyzed its causes, summarized and compared the existing control measures of lake eutrophication, and pointed out that the ecological remediation was the best way. Therefore, lake restoration must be conducted subsequent to control of nutrient loading, ie. control the input of pollutant first, then attempt ecological restoration.
