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。
Analyzed the social and economic development of the Lake in Chaohu from 2001 to 2013 and the change of water quality of Chaohu Lake during this period. The relationship between population, GDP, COD, TP, TN, chlorophyll and eutrophication index in Lake Chaohu was analyzed using correlation analysis method. The results show that from 2001 to 2013, the population and GDP of the Central Chaohu Lake area showed a trend of increasing year by year, and the overall water quality of Chaohu Lake water body tended to be better. Correlation analysis showed that there was a negative correlation between GDP and population in the Chaohu Lake area and other indexes of Chaohu Lake water quality except for positive correlation (not significant) with the Chaohu Lake area GDP and eutrophication. This shows that over the past decade the overall environmental quality of Chaohu Lake has been effectively controlled.
