选取总氮（TN）、总磷（TP）、高锰酸盐指数（CODMn）、透明度（SD）和叶绿素a五项,利用综合营养状态指数法评价马踏湖富营养化程度,并选取总氮、氨氮、化学需氧量、五日生化需氧量、高锰酸盐指数等主要指标年均值的比值作图分析,得出马踏湖污染状况。在此基础上分析马踏湖水体富营养化原因,并提出降低马踏湖富营养化现象的措施、对策。

Total nitrogen（TN）,total phosphorus（TP）,potassium permanganate index（CODMn）,transparency（SD） and chlorophyll five items were selected to evaluate the eutrophication degree of Mata Lake by using index method of comprehensive nutrition evaluation.The pollution status of Mata Lake were obtained by drawing figures to compare the annual average values of major indexes,including total nitrogen,ammonia nitrogen,chemical oxygen demand（COD）,5 days biological oxygen demand（BOD） and potassium permanganate index.The reasons for the eutrophication of Mata Lake was studied based on analysis and measures to improve the eutrophication were put forward.
