摘　　要：目的:探讨分析造成某人工湖水体富营养化的原因。方法:通过某校园人工湖泊水体中总磷(TP)、化学需氧量(COD)、透明度(SD)等水质参数进行实际检测,采用参数综合判断法进行综合分析。结果:目前人工湖仍处于富营养状态,但已经出现富营养衰退的现象。全湖的总磷(TP)、化学需氧量(COD)的含量平均比较高,湖水表面的溶解氧(DO)呈现过饱和状态。结论:水体富营养化的主要原因是由于外界输入过量的氮磷营养物质,在适当的温度、光照下,藻类过量生长繁殖造成的。Objective：Analyzes the reasons of some artificial lake eutrophication.Methods：On the basis of detection of total phosphorus（TP）,chemical oxygen demand（COD）,transparency（SD）,an integrated comprehensive analysis of judgment has been used to understand the artificial lake water body＇s overall condition.Results：The results showed man-made lake is currently still in the eutrophic state,but the phenomenon has emerged nutritious recession.The whole lake phosphorus（TP）,chemical oxygen demand（COD）,and the level of the lake surface dissolved oxygen（DO） showed oversaturated.Conclusion：Eutrophication is mainly caused by excessive growth and reproduction of algae under excess of nitrogen and phosphorus in the external input of nutrients at the right temperature and sunlight.
