OMPARISON OF FORAMINIFERAL TAPHOCOENOSE ASSEMBLAGES SEDIMENTS FROM SOUTHERN BOHAI SEA
-
摘要:
对渤海南部的84个表层沉积物样品中的底栖有孔虫埋藏群落进行了统计分析，研究结果显示这一海域底栖有孔虫冷水种和广温、广盐种占据明显优势。利用Q型因子分析获取了4个主因子及其所属有孔虫组合：Protelphidium turberculatum - Buccella frigida组合主要体现了渤海底层冷水团的控制；Cribrononion subincertum - Buccella frigida组合受黄海暖流余脉与底质粒度的双重影响；Ammonia becarii var.- Ammonia aomoriensis组合主要受控于具低盐特性的渤海沿岸水团；Elphidium advenum - Textularia foliacea组合主要受底质类型的影响。总之, 研究区内盐度、温度以及底质类型对底栖有孔虫分布的影响十分明显，而水深分带性在这一海域并不明显。
Abstract:84 surficial sediment samples obtained from the southern Bohai Sea were selected for revealing the distribution pattern of the benthic foraminifera and their relationships with the marine environmental parameters of the sediments. The data suggests that the study area was dominated by the foraminiferal species with high tolerances to low temperature and low salinity. Moreover, 38 species/genera with relatively higher abundances were chosen for Q-mode factor analysis, and then 4 varimax factors corresponding respectively to 4 foraminiferal assemblages were obtained. Comparison between the assemblages and environmental parameters leads to the following conclusions: first, the Protelphidium turberculatum-Buccella frigida assemblage dominates the cold bottom water mass in the central Bohai Sea; second, the Cribrononion subincertum - Buccella frigida assemblage is mainly controlled by both the remanent Yellow Sea warm current and the grain size of bottom sediment; third, the Ammonia becarii var.- Ammonia aomoriensis assemblage was dominated in the coastal water masses with low salinity; and forth, the Elphidium advenum - Textularia foliacea assemblage was mainly constrained by the grain size of sediment. In general, water depth and sea floor topographic fluctuation show little influence on the distribution pattern of foraminifera. Instead, temperature, salinity, and sediment grain size are the main factors which decide the distribution pattern of benthic foraminifera in the study area.
