Wind-driven wave disturbance is one of the environmental factors that shapes the formation of Microcystis blooms. Here we present data on the effect of different disturbance modes (continuous vs intermittent disturbances) on colony size, biomass and dominance of Microcystis in Lake Taihu under field conditions. Small submersible pumps were used to simulate different disturbance modes at turbulent dissipation rate (ε) of 2.98 × 10⁻⁶ m² s^–3. Our results show that the mean colony sizes of Microcystis in intermittent and continuous disturbance group were 1.94 and 1.23 times that of the control group, respectively. The mean densities of Microcystis in intermittent and continuous disturbance group were 4.23 and 2.91 times that of the control group, respectively. The mean proportion of Microcystis to total algae abundance in control group and continuous disturbance group changed from 78.3% at beginning of the experiment to 4.5% and 9.1% at the end of the experiment. However, the proportion of Microcystis to total algae cells in intermittent disturbance group was 65.7–94.3% during the whole experiment. The results demonstrated intermittent disturbances favored colony morphology, biomass and dominance of Microcystis. Our results suggested that intermittent disturbance benefited the formation of Microcystis bloom and was important in the development of predictive models for toxic cyanobacterial blooms under changing climates in shallow lakes.

风波干扰是影响微囊藻水华形成的环境因素之一。在这里，我们介绍了田间条件下不同干扰方式（连续干扰与间歇性干扰）对太湖微囊藻群落大小，生物量和优势的影响的数据。小型潜水泵用于模拟在2.98×10 ^-6 m ² s ^–3的湍流耗散率（ε）下的不同扰动模式。我们的结果表明，间歇性和连续性干扰组中微囊藻的平均集落大小分别是对照组的1.94和1.23倍。微囊藻的平均密度间歇性和连续性干扰组的血糖分别是对照组的4.23倍和2.91倍。对照组和连续扰动组中微囊藻占藻类总丰度的平均比例从实验开始时的78.3％变为实验结束时的4.5％和9.1％。但是，在整个实验中，间歇性干扰组中微囊藻占藻类细胞总数的比例为65.7–94.3％。结果表明间歇性干扰有利于微囊藻的菌落形态，生物量和优势。我们的结果表明间歇性干扰有益于微囊藻的形成 在浅水湖泊变化的气候下，对有毒蓝藻水华的预测模型的开发非常重要。
