Exterior Pollutions of Taihu Eutrophication and Its Control Measures

太湖流域是我国经济最发达的地区之一,又是我国著名的旅游胜地,随着社会和经济的发展,太湖流域的GDP总值在全国占有重要的地位,但是,由于众多人为因素的影响,已导致太湖生态环境急剧恶化,特别是水体污染与富营养化情况日趋严重,分别从点源污染和非点源污染2个方面分析了太湖富营养化的成因,并针对这2个方面从外源控制的角度提出了相应的控制对策及治理的办法,阐述了控制及治理等方面现有的不足,并对此提出了一系列可行性建议与展望。

Taihu drainage basin is one of the developed areas and a famous scenic spot in China, With the social and economic development, the gross domestic product of the lake basin occupies and impotant pisition in the whole country, but, because of many artificial factors, the eco-enviroment has been drastically deteriorated especially pollutions. and eutrophication of Taihu are becoming increasingly serious.
