摘要:
浮游植物薄层是指位于水体次表层、厚度从几厘米到几米的高丰度浮游植物分布层。与大洋相比,在河口、海湾和近海的浮游植物薄层往往分布浅、强度大,具有明显的时空变化。浮游植物薄层的形成和维持不仅受到层化、楔入、剪切等物理过程的调控,也与浮游植物的生长、聚集及浮游动物的差异化捕食等生物生态学过程有关,目前围绕浮游植物薄层的形成机制已提出了趋旋俘获等假说。浮游植物薄层对其生长、繁殖、防御等具有重要意义,有的浮游植物薄层聚集了大量的有毒有害藻,与有害藻华的发生关系密切。深入研究浮游植物薄层的成因,将为阐明有害藻华的发生机制和有效监测提供重要依据。

Abstract:
The thin phytoplankton layer (TPL) refers to a high-biomass phytoplankton layer with a thickness from centimeters to meters present in subsurface waters. Compared to the TPL in the open ocean, those TPLs in estuaries, bays, and coastal oceans are generally located at shallow depths and have higher densities. The formation of a TPL is closely related to physical processes such as stratification, intrusion, and shearing. Biological processes like buoyancy, swimming, and in situ growth also play important roles. Mechanisms such as gyrotactic trapping have been proposed to explain the formation of a TPL. The formation of a TPL has significant ecological implications through regulation of the growth, reproduction, and defense of phytoplankton. Moreover, the TPL is closely related to the occurrence of harmful algal blooms (HABs), since a large number of toxic or harmful algae are present in TPLs. An in-depth study of TPLs will provide an important basis on which to clarify the mechanisms of HABs and to develop effective monitoring and early-warning capability against HABs.
Key words:  thin phytoplankton layer  marine ecology  harmful algae bloom
