Abstract
In order to understand the characteristics and causes of water quality change in Xingyun Lake during the dry and rainy seasons,the paper analyzed the seasonal variation of water quality in Xingyun Lake by comprehensive nutrient state index and comprehensive pollution index,and analyzed the correlation between comprehensive nutrient state index,comprehensive pollutionindex and water level and water temperature of Xingyun Lake by Spearman model.The results showed that the variation of the comprehensive pollution index in the dry and rainy season were consistent with the changes of the Xingyun Lake body,that is,the pollution in the rainy season was higher than that in the dry season.Lake water temperature was significantly positively correlated with the comprehensive nutrition index and comprehensive pollution index,while lake water level was significantly negatively correlated with the comprehensive nutrition index in 2019.It is concluded that the water quality of Xingyun Lake in rainy season is generally worse than that in dry season,which is influenced by the pollution input of rivers into the lake,the rise of water temperatureand the fall of water level.Suggestions were put forward to strengthen pollution control at the source,ensure ecological flow,and implement internal pollution control,so as to provide reference for continuous improvement of water quality of Xingyun Lake in the future.关键词
