| 摘 要： | 对2006年8月取自北黄海的302个表层沉积物样品中的底栖有孔虫群落进行了分析,结果表明:北黄海底栖有孔虫群落以适应低温、低盐的冷水种和广温、广盐种为主,胶结质壳底栖有孔虫含量明显高于我国其他海区。利用Q型因子分析提取了5个主因子,通过将主因子代表的底栖有孔虫组合与环境影响因子之间的对比印证,揭示了其内在联系,北黄海底栖有孔虫分布的决定性因素是表层沉积物的粒度,而温度和盐度则起到次要作用,该海区水深变化对底栖有孔虫分布的影响没有明显的规律性。

| Abstract: | 302 surficial sediment samples obtained from the North Yellow Sea in August 2006 were selected to study the distribution of benthic foraminifera and its relation to the modern marine environment.The benthic foraminiferal fauna was mainly composed of species with high tolerance towards low temperature and low salinity.Moreover,percentages of species were obviously larger than in other Chinese seas.56 species/genera with relatively high abundances were chosen to carry out Q-mode factor analysis,5 varimax fact... |
