【摘要】 表征藻类生物总量的藻密度与水质理化指标的相关性的研究报道较少。2012年夏季对滇池网格布点40个,按照《水和废水监测分析方法(第四版)》对浮游藻类的密度和水质理化指标进行了监测。结果表明:共发现滇池游藻浮游藻类9个门66属157种。对6项理化指标和5项生物指标构成的30对关系进行了一元线性回归,相关性最好的7对关系依次为:TN-藻密度(r=0.779 4)>TN-蓝藻密度(r=0.752 5)>TP-藻密度(r=0.701 8)>TP-蓝藻密度(r=0.660 9)>可溶性TN-蓝藻密度(r=0.567 2)>可溶性TN-藻密度(r=0.546 1)>可溶性TN-蓝藻比例(r=0.535 1);与藻类生物总量最相关的理化指标是TN,其次是TP,再次是可溶性TN。更多还原

【Abstract】 There were few reports on the relationship between algae density and chemical indexes of water quality.The monitoring on Dianchi Lake in summer of 2012 showed that the most relative indexes pairs were TN-algae density(r=0.779 4)>TN-cyanophyta density(r=0.752 5)> TP-algae density(r=0.701 8)>TP-cyanophyta density(r=0.6609)>soluble TN-cyanophyta density(r=0.567 2)>soluble TN-algae density(r=0.546 1)>soluble TN-cyanophyta percentage(r=0.535 1),among the 30 pairs of relationship multiplied by 6biological indexes and 5chemical indexes.According to the above results,the most relative indexes pairs between chemical indexes and biological indexes were firstly TN,secondly TP,and thirdly soluble TN.更多还原
