| Abstract: | Based on monitored data, the paper analyses the correlation of Chl-a with TN, TP and other variables by means of linear regression, Pearson correlation and hierarchical clustering of the parameters. It is revealed that TN is the main factor that influences the growth of algae during the period of algae bloom. Eutrophication of the river and lake in urban district of Beijing are developing. |
