Marine biodiversity is changing in response to altered physical environment, subsequent ecological changes as well as anthropogenic disturbances. In this study, phytoplankton samples in situ collected in the Bering Sea in July of 1999 and 2010 were analyzed to obtain phytoplankton community structure and spatial-temporal variation between the beginning and end of this decade, and the correlation of phytoplankton community dynamics and environmental factors was investigated. A total of 5 divisions, 58 genera and 153 species of phytoplankton belonging to 3 ecological groups were identified. The vast majority of phytoplankton consisted of diatoms accounting for 66.7% of the total species and 95.2% of the total abundance. Considering differentiation in spatial extent and phytoplankton sample types, there were subtle changes in species composition, large altering in abundance and significant variation in spatial distribution between two surveys. The abundance peak area was located at the Bering Strait while sub peak was found at the Bering Sea Basin. The boreal-temperate diatom was the dominant flora, which was subsequently replaced by eurythermal and frigid-water diatom. Phytoplankton community in the Bering Sea was not a simplex uniform community but composed of deep-ocean assemblage and neritic assemblage. The deep-ocean assemblage was located in the northwestern Pacific Ocean and Bering Sea Basin, dominated by boreal-temperate species（Neodenticula seminae, Thalassiothrix longissima, Amphiprora hyperborean, Chaetoceros atlanticus, Thalassiosira trifulta, etc.） and eurychoric species（Thalassionema nitzschioides, Ch. compressus, Rhizosolenia styliformis, etc.）, and characterized by low abundance, even interspecies abundance allocations, diverse dominant species and high species diversity. The neritic assemblage was distributed on the continental shelf and slope of Bering Sea and was mainly composed of frigid-water species（***？ldii, Ch. furcellatus, Ch. socialis

present study is based on the analysis of the data collected in 10 dnas during the periods of 2 surveys (from May 1992 to January 1993 and from August 1993 to May 1994). The results show that the number ofphytoplankton in highly eutrophic waters of the Maluan Bay is low, Only 6-35 spotes from each cruise and 66species in total fain the 2 surveys. The phytoplanha abundanCe is high. The mean cell densities of phytoplanktonfrom the net samples were 21 386x 104 cells/m3 for the first sUrVey and 110 136 x 104 cells/m3 for the second survey,that fm the water Samples was 1 150. 7 cells/cm3. The mean concentration of chlorOPhyll a reachs 6. 67 mg/*** the species diversity (H') and evennes (J) were low, only 0. 78 and 0. 28, restwhvdy. The temporal and spatial fluctuation of the cell denSity of phytoplankton was quite wificant, caused banly by contribution of pennate diatom Nitzschia delicatissima that often abudanily occurred in a ofed waters rich in organic matter and could be takenas an ecologic indicator of highly eutrophic harbour. The axistence of good correlation between the cell density ofNitzschia delicatissima and some environmental variables (e. g. Po43 - P and COD, etc. ), and the heterotrophic tendancy of this species are discussed, too.

在整合两岸学者有关台湾海峡的浮游植物物种多样性研究的基础上,作者提出了一份台湾海峡小型浮游植物物种名录,共包含620种,并按照其生态类群和赤潮种类进行了区分。同时以1984年5月至1985年2月在福建海岸带和台湾海峡共86个观测站四个季度月浮游植物的344份调查资料为基础,来阐明物种分布的基本格局和丰度变化的时空趋势。结果表明:此次调查所鉴定的299种浮游植物中硅藻门为199种,其丰度占浮游植物丰度的99.25%,对本海区浮游植物的分布起支配作用。浮游植物的种类数和丰度年高峰均在夏季。就平面分布而言,海峡区的种类数多于近岸区,与海水的温度和盐度成正相关关系;而近岸区的丰度高于海峡区,Shannon-Wiener指数和均匀度则是海峡区高于近岸区。
