摘要

摘要: 分别于2011年夏季(6月)、秋季(11月~12月)在南黄海(31°58.278'--35°58.122'N, E 120°20.600'--124°29.957')进行了两次水文、化学和生物的综合调查.应用Utermöhl沉降法进行了浮游植物水样的丰度计数和物种鉴定.结果表明浮游植物主要由硅藻、甲藻刻画.其中,夏季航次具槽帕拉藻(Paralia sulcata)和具齿原甲藻(Prorocentrum dentatum)占绝对优势,总细胞丰度介于0.074-107.733×10³ cells/L,平均值为9.057×10³cells/L.两个浮游植物丰度高值区分别出现在调查区西北部和长江口.秋季,具槽帕拉藻(Paralia sulcata)为最优势物种,总丰度介于1.035-8.985×10³ cells/L,平均值为3.263×10³ cells/L.表层浮游植物分布较为均一.常见物种与环境因子间的典范对应分析(Canonical Correspondence Analysis, CCA)结果表明,浮游植物在夏秋季对营养盐的响应情况不同.具槽帕拉藻(Paralia sulcata)在秋季与温度、盐度呈现很强的负相关,夏季则无此相关性.

Abstract: The phytoplankton water samples were collected in two multidisciplinary investigations which were carried out during summer (June) and autumn (November to December) of 2011. Phytoplankton species composition and abun-dance data were accomplished by Utermöhl method. The phytoplankton community was dominated by diatoms and dinoflagellates in the southern Yellow Sea (YS) in summer and autumn. In summer, Paralia sulcata and Prorocen-trum dentatum were the predominated species, the cell abundance ranged from 0.074 to 107.733×10³ cells/L with an average of 9.057×10³ cells/L. Two phytoplankton high abundance appeared in northwest part of the survey area and the Changjiang River Estuary, respectively. In autumn, Par. sulcata became the predominant species, and the phyto-plankton cell abundance ranged from 1.035×10³ to 8.985×10³ cells/L, the average was 3.263×10³ cells/L. The phytopl-ankton abundance in surface layer presented the homogeneous distributions. Canonical Correspondence Analysis (CCA) method was applied for discovering the relationship between environmental factors and the common found phytoplankton species. The responses of phytoplankton to nutrients were varied between summer and autumn. The abundance of most predominant species, Par. sulcata was strongly correlated to temperature and salinity in autumn, but not the case in summer.
