摘　　要：为了解决星云湖水质富营养化问题,提出研究污染源磷对星云湖水质富营养化的影响。首先分析了富营养化对湖泊产生的危害,利用逐日平均温度数据和逐日降雨量数据在水平衡方程的基础上建立GWLF模型,模拟分析星云湖水质富营养化污染负荷。采用Microsoft Excel分析污染源磷的时空变化,并采用线性回归分析法分析磷营养盐与多样性指数、叶绿色a和浮游植物生物量之间存在的关系,研究了不同季节下浮游植物与总磷相互关系的变化情况,为解决星云湖水质富营养化问题提供了相关依据。In order to solve the problem of water eutrophication in Xingyun Lake,the paper studied the influence of pollution source phosphorus on water eutrophication in Xingyun Lake.Firstly,the harm of eutrophication to lakes is analyzed.Based on the water balance equation,GWLF model is established by using daily average temperature data and daily rainfall data to simulate and analyze the pollution load of water eutrophication in Xingyun Lake.Microsoft Excel was used to analyze the temporal and spatial changes of phosphorus in pollution sources,and linear regression analysis was used to analyze the relationship between phosphorus nutrients and diversity index,leaf green A and phytoplankton biomass.The relationship between phytoplankton and total phosphorus in different seasons was studied,which provided relevant basis for solving the eutrophication problem of Xingyun Lake.
