太湖梅梁湾富营养化相关问题探讨

Discussion on relative questions of eutrophication in Meiliang lake

太湖水体富营养化问题已严重威胁着太湖流域社会经济发展,特别是梅梁湾湖区尤为严重。以实测资料为基础,分析了太湖富营养化的环境影响因子,得出以下结论:磷为梅梁湾湖区主要的限制性因子;光照、水温为该区富营养化重要影响因素,但不是主要的限制性因子。CODMn与富营养化关系密切,但需进一步探讨其影响实质。

The eutrophication has threaten the development of economy in Taihu watershed specially in Meiliangwan.The study analysis the main factors which affect occurrence of eutrophication. Some conclusions are drawn:TP is limitative factor. Illumination, temperature are important factors not limitative ones. The relation between COD_ Mn and eutrophication is not clear, need to be explored deeply.
