中文摘要：

海洋水体中浮游植物粒径等级的差异能反映其功能类型的不同,浮游植物粒径等级的探测对水生态系统中浮游植物功能多样性及浮游植物生物地理化学功能的研究具有极其重要的意义。本文综述当前浮游植物粒径等级的遥感探测算法,阐述各算法的步骤过程及其特点,并分析了优缺点。基于此,针对我国近海及海岸带水体,提出海洋浮游植物粒径等级（phytoplankton size classes,PSCs）遥感研究今后需要开展的工作。

英文摘要：

The difference if phytoplankton size classes（PSCs）in marine waters reflects phytoplankton function diversity,of which the study is of significance for understanding the structure of phytoplankton community,and revealing biogeochemical processes of water ecosystem.This article reviews current researches on remote sensing algorithms of PSCs in marine waters.The processes of existing remote sensing algorithms are addressed in detail,and their advantages and disadvantages are also analyzed,based on which,several important aspects of research work are proposed for developing remote sensing algorithms suitable for coastal waters of China.
