人工强制混合技术通过调控水动力条件对藻类生长和结构产生影响，已在全球湖库应用多年，国内外相关研究较多。然而，缺少综述性整理，尤其是对不同技术应用前提、适用条件及优缺点等认识不够，导致技术错用而没有发挥其优势，出现了控藻效果差，甚至无效等现象。本文主要结论如下:①该类技术通过调控混合层深度(Zmix)控制藻类生物量与结构变化，其应用效果主要与湖库水深、混合器平面布设、系统运行方式和混合效率有关;②该类技术控藻周期(藻密度削减95％以上)约为2周，控藻推荐的Zmix阈值＞15m;③该类技术主要适用于深水型水体，遴选控藻技术时应考虑适用条件、成本效益等。
Review on the control of algal blooms via artificial mixing:theory,technologies and mechanism
Artificial mixing influences the algal growth and structure by regulating hydrodynamic conditions,which has been applied to control the algal blooms in the global lakes and reservoirs for many years.The related researches at home and abroad have been widely reported,but the systematic review is rare.Especially,due to the limited understanding of the application precondition,application conditions,and advantages and disadvantages of different technologies,these technologies were misused and did not play its advantages,which resulted in the poor and even ineffective effect on algal control.The main conclusions includes:(1)Artificial mixing controls the change of algal biomass and structure by regulating mixing depth(Zmix),whose application effect is mainly related to the water depth,horizontal distribution of mixing devices,system operation regimes,and mixing efficiency;(2)The algal control period(i.e.,the reduction of more than 95％of algal cell density)of Artificial mixing is about 2weeks,and the recommended Zmix threshold for algal control is more than 15m;(3)Artificial mixing is mainly suitable for the deep waters,and the selection of algal control technologies should consider their application conditions,cost effectiveness and so on.
