镜泊湖富营养化评价及防治对策研究

摘要

镜泊湖富营养化的主要原因为营养物质的过量输入,其次是温度、光照、水动力条件等物理因素,第三为生态失衡.通过对其水质系统分析与评价,得出镜泊湖水质初期的处理措施合理,并逐年变好趋于稳定,水体处于中营养状态.为进一步改善镜泊湖水质,共提出三大措施,一为建立污水处理厂,二为充分利用水生植物、生态浮床措施,三为辅助人工湿地、生物操纵等生态修复方式,减少二次污染,使镜泊湖水体恢复到原来的状态.%The main sources of Jingpo Lake eutrophication is the life sewage;the second is the river and the water inflow Jingpo Lake,third,the non-point source pollution.After the comprehensive understanding Jingpo Lake environment,results show that the initial processing measures to suit to Jingpo Lake,good trend year by year and water quality stable,in the nutritional status of water.To further improve Jingpo Lake water quality,there are three measures are put forward,the first,establish sewage treatment plant,the second,make full use of aquatic plants,ecological floating bed,the third,constructed wetland and biological control ways of ecological restoration,as far as possible to reduce secondary pollution,make these water back to its original state.
