Popis:	垂向湍流、温、光等是影响藻类生长和垂向分布的关键因素。基于大型浅水湖泊(太湖)的背景物理场(辐射、水深、水温和消光等)，利用藻类生长-扩散模型的敏感性试验，探讨物理过程对浅水湖泊中下沉藻的垂向分布的影响机制。水温是次表层叶绿素峰值(Subsurface Chlorophyll Maxinmum：SCMax)或谷值(Subsurface Chlorophyll Minimum：SCMin)形成的限制性条件；当水温大于阈值时，随深度的增大，过强光能抑制藻类的生长转变为弱光限制藻类的生长是SCMax形成的关键；垂向湍流的裹挟作用是弱化SCMax强度的关键过程。该研究有利于厘清物理过程对藻类群落演替的作用机制，强化对水生态系统的修复效果。
