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 6 biological indexes and 5 chemical 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
