Picoplankton biomass was larger than nanoplankton biomass in every sampling station. Autotrophic pico- and nanoplankton decreased with depth, while heterotrophic ones did not showed conspicuous decrease. Correlation between autotrophic picoplankton and heterotrophic nanoplankton was significantly positive and, therefore, these two plankters have the same characters for their favorable environments.Total microplankton biomass was slightly larger in the eastern side of East China Sea and partition of micro-diatom was distinctively larger in the same region. Maximum layer of total microplankton occurred shallower than that of chlorophyll a. Naked cells dominated in both dinoflagellate and ciliate groups.Among ciliate plankters, subclass Choreotrichia, especially, suborder Oligotrichina dominated in the surface layer. These ciliates decreased with depth and other subclass ciliates were dominant in the deeper layer. Loricated ciliate, suborder Tintinnina, was subordinated throughout the water column in every station. Some ciliates were identified into species level and each individual showed different occurrence pattern against salinity and temperature.

在每个采样站，皮科普兰克顿生物量比纳米浮游生物量大。自养皮基和纳米浮游生物随深度的降低，而异养的杂种并未显示出明显的降低。自养基上皮膨胀和异养纳米全膨胀之间的相关性显着积极，因此，这两个木板在其有利的环境中具有相同的特征。东方海洋东部的多个微量浮游生物的生物量略大，在同一地区的微型跨区域较大。总微量浮游生物的最大层比叶绿素a的浅层层浅。裸细胞在鞭毛藻和纤毛群中占主导地位。在纤毛木板，亚类舞蹈曲，尤其是在地表层中占主导地位的亚顺序寡聚。这些纤毛随深度降低，其他亚类纤毛在更深的层中占主导地位。 Loricated Ciliate suborder tintinnina在每个站的水柱中都服从于服从。一些纤毛被鉴定为物种水平，每个人在盐度和温度下显示出不同的出现模式。
