This paper uses statistic and nonlinear regression approaches to describe and evaluate the changes of the cyanobacteria growth in the Guishui lake in Beijing remote suburb. The results show that high ratios of TN/TP (>20), and low concentrations of TP (<;0.3 mg/L), and COD (<;30 mg/L) may constrain the growths of the cyanobacteria in the lake. The cyanobacteria growths are positively related...
During the last two years, data sets from three groups and twelve sampling points were used to investigate historical changes between the concentration of the cyanobacteria and the concentrations of total nitrogen (TN), total phosphorus (TP), TN/TP, chemical oxygen dawdling (COD), NO3-, pH, and Chl-a in a shallow temperate zone lake (Guishui Lake, Beijing). The aim of this paper was to evaluate changes...
