摘要
Wind can lead to large-scale heterogeneity in the horizontal distribution of phytoplankton in lakes. By analyzing the stress mechanism of the mat-shape algae on the surface of water, we treat the algae layer as a kind of liquid and establish a two-layer fluid model. A basic relationship between wind speed and algae moving velocity is deduced theoretically, which indicates that the drift velocity of mat-shape algae changes with wind speed in a quadratic function. Finally, the theoretical result is examined by the observation data and fits well.; Wind can lead to large-scale heterogeneity in the horizontal distribution of phytoplankton in lakes.
