收集了1960年至2008年滇池水质及社会、经济指标，应用相关性分析方法，对滇池流域人口、昆明市GDP的增长与滇池TN, TP, CODMn之间的关系进行了研究。结果显示，滇池水体富营养化程度与滇池流域人口、昆明市GDP密切正相关，流域人口增加、经济发展是滇池水体富营养化的主要原因。社会经济发展对滇池草海水体所造成的压力高于外海，且草海水质有继续恶化的趋势。由于滇池综合治理工作的不断推进，特别是2000年滇池水污染防治“十五”计划实施以来，滇池流域社会经济发展对滇池外海水质的影响有所减轻，外海水质继续恶化的趋势得到初步遏制。

The water quality and the social economic data from 1960 to 2008 were collected, correlation analysis were used to study the relationship between the population, GDP and the TN, TP, CODMn. The results shows that there is close positive correlation between the socio-economic development factors and the Dianchi Lake's water quality, the rapid population growth and economic development is one of major reasons which cause the Dianchi Lake pollution. Caohai part was placed more severe pressure by socio-economic development than Waihai part, and the extent of eutrophication of Caohai part seems to be increasing. But on account of the Dianchi Lake's comprehensive pollution prevention and treatment, Dianchi lake's water quality has been less impacted by socio-economic development and the trend of pollution in Waiha has been basically curbed since the "The 10th Five-Year Plan of Dianchi Lake basin pollution prevention and treatment"  started in 2000.
