| 摘 要： | 综合考虑光、营养盐、温度对微囊藻生长的影响,建立了太湖静止水体微囊藻垂直运动模型,分析藻类在水体生态系统复杂因素作用下的运动变化规律.通过与Kromkamp-Walsby模型比较发现,太湖静止水体微囊藻垂直运动模型模拟结果合理可靠,模型计算结果显示藻半径大的微囊藻更容易运动到水体表面,在持续大风或持续阴天后水华更易暴发.

| Abstract: | With consideration of the effects of light,nutrients,and temperature on the growth of Microcystis,a vertical migration model of Microcystis under a static water body in Taihu Lake was developed in order to study the algae migration affected by complex factors in the aquatic ecosystem.Compared with the results of the Kromkamp-Walsby model,it was found that the results of the proposed model were reasonable and reliable.The calculated results show that Microcystis with a large radius could migrate to the water surface more easily than that with a small radius,and algal blooms would easily occur after sustained strong winds and cloudy days. |
