摘要
The research analyzed social and economic development around Chao Lake as well as changes of water quality in Chao Lake and explored the relation- ships of local population and GDP with water chemical oxygen demand （COD）, total phosphorus （TP）, total nitrogen （TN）, chlorophyll and eutrophication index. The re- sults showed that population around Chao Lake and GDP kept growing from 2001 to 2013, and water quality was improving. In addition, correlation analysis indicated that except of water eutrophication, GDP and population showed inverse correlation with other indices, demonstrating that water quality has been effectively controlled in Chao Lake recently.
分析了2001~2013年环巢湖地区的社会经济发展状况以及在此期间巢湖水体的水质变化情况。应用相关性分析方法分析了环巢湖地区人口、GDP与巢湖水体COD、TP、TN、叶绿素和富营养化指数之间的关系。结果显示,2001~2013环巢湖地区的人口和GDP呈现逐年增长的趋势,巢湖水体水质总体趋于好转。相关分析表明除了与环巢湖地区GDP与巢湖水体富营养化呈现正相关（不显著）以外,环巢湖地区GDP、人口与巢湖水质其他指标呈现负相关。这表明近十几年来巢湖水体环境质量总体得到了有效控制。
