摘要
巢湖作为城市重要饮用水水源地,受到蓝藻侵扰,严重影响当地居民饮用水安全.通过对巢湖2014年4-8月份水质检测数据进行分析,评价巢湖蓝藻聚集程度.并应用SPSS多元逐步回归分析对巢湖水质指标与叶绿素(Chla)进行研究.结果表明:4月份巢湖富营养程度为中营养等级,5-8月份均为轻度富营养等级,7月份TLI指数最高.通过回归方程得出水体TN含量是限制巢湖蓝藻聚集的首要因素.最后在评价结果的基础上提出了控制巢湖蓝藻的对策.
As an important drinking water source,Chaohu Lake is invaded by cyanobacteria, seriously impact on local residents＇ drinking water safety. According to water quality monitoring data of Chaohu Lake during April to August 2014, evaluation of Chaohu Lake algae aggregation degree. Using multiple stepwise regression analysis of SPSS analysis software to analyze Chao- hu Lake water quality index and chlorophyll （Chla）. The results show that the eutrophication degree in Chaohu Lake is Mesotropher level in April, are light eutropher level during May to August,and the highest TLI index in July. Through the regression equation TN content in the water is the primary factor to limit algae aggregation in Chaohu Lake. Finally, algae control countermeasures in Chaohu Lake are put forward on the basis of the evaluation results.
