英文摘要	This study found that intermittent disturbance combined nitrogen and phosphorus adding promoted colony size and abundance increase of Microcystis flos-aquae. This result suggest that intermittent disturbance combined N and P adding plays an important role in the formation of Microcystis blooms in freshwater ecosystems. Nutrients and disturbance are both important environmental factors in the freshwater ecosystem. Here we present data on the effects of intermittent disturbance (ID), nitrogen and phosphorus adding (+N+P), and intermittent disturbance combined N and P adding (ID+N+P) on colony size and abundance of Microcystis flos-aquae in lab experiments. Results showed that the mean colony sizes of M. flos-aquae in ID+N+P group were1.68, 1.56, 1.17 times that in the control, +N+P, ID groups, respectively. Moreover, the average number of M. flos-aquae in ID+N+P group were 1.47, 1.19, 1.42 times those in the control, +N+P, ID groups, respectively. The average concentration of EPS (extracellular polysaccharides) in ID and ID+N+P group was significantly higher than those in control and +N+P groups. Results demonstrated that intermittent disturbance combined N and P adding promoted colony size and abundance of M. flos-aquae. These results suggest that intermittent disturbance combined N and P adding plays an important role in the formation of Microcystis blooms in freshwater ecosystems.
