摘    要:根据2008年5-9月专项监测数据,分析蓝藻水华高发期淀山湖叶绿素a浓度的动态变化,及其与pH、溶解氧、TN、TP等环境因子的相互关系.结果表明,淀山湖蓝藻水华高发期叶绿素a存在明显的时间变化和空间分异,特别是叶绿素a的峰值共对应了3次水华暴发过程.其叶绿素a对数与总磷对数呈极显著正相关,与硝酸盐氮、TN/TP呈负相关...

关 键 词:淀山湖  叶绿素a  蓝藻水华  环境因子  相关分析

Abstract:According to the monitoring data at 13 sampling sites of Lake Dianshan from May to September 2008,the relationship between chlorophyll-a concentrations and environmental factors(water temperature,pH,DO,TN and TP) was investigated.The results indicated that there was an obvious temporal and spatial variation of chlorophyll-a.The first cyanobacterial bloom in 2008 occurred on July 23 at Qiandungang site and Youyongchang site.The most severe bloom covered a total area of 17km2 on August 27.Significantly positi...
Keywords:Lake Dianshan  chlorophyll-a  cyanobacterial bloom  environmental factor  correlation analysis
