Variation of dissolved oxygen in the experiments of occurrence & disappearance for Microcystis bloom

摘要：

　　Microcystis blooms were simulated in the experiments through controlling the initial phosphor and nitregen concentrations,and the complex of environmental and nutrient conditions,respectively.The results show that the differences of measured and saturated dissolved oxygen vary corresponding to the concentrations of chlorophyll a,which indicates that the variation of dissolved oxygen is mainly owing to Microcystis photosynthesis,respiration and death decomposition processes.The correlations for the differences of measured and saturated dissolved oxygen and the concentrations of chlorophyll a are mostly significant.The dynamic model for dissolved oxygen based on the growth kinetics of phytoplankton could be displayed by the exponential model.
