全面分析了南湖湖泊系统中营养物之间、营养物与藻类生长之间的相互关系，探讨了各种环境因子对南湖富营养化的影响，结合藻类增长潜力试验结果确定南湖富营养化的主要控制因子。结果表明，光、温度、碳、氮不能成为南湖富营养化的主要控制因子。

The relationship among different nutrients and the relationship between the nutrients and algae growth in Nanhu Lake were comprehensively analyzed.The influences of various environmental factors on the eutrophication in Nanhu Lake were investigated and the main contrtolling factors of the eutrophication in the lake identified,combined with experiments of algae growth potential.It was shown that the main controlling factors of eutrophication in Nanhu Lake are light,temperature,carbon and nitrogen while the control of phosphorus is key to the control of eutrophication in Nanhu Lake.
