山东半岛东北部海域表层沉积物底栖有孔虫分布特征及影响因素
Distribution characteristics and influencing factors of benthic foraminifera in surface sediments in the northeastern sea area of Shandong Peninsula
摘要
Abstract
Foraminifera are the most widely studied micropaleontological group in marine environment and has important significance in marine environment indication.In this paper,the distribution of foraminifera in surface sediments near Shandong Peninsula is described.The study area is dominated by benthic foraminifera.The result of factor analysis,showed that the benthic foraminifera in the study area could be divided into four assemblages.Assemblages 1 is Verneuilinulla advena-Astrononion gallowayi-Cribrononion gnythosuturatum,Assemblages 2 is Astrononion gallowayi-Buccella frigida-Elphidium advenum,Assemblages 3 is Hanzawaia convexa-Buccella fri-gida-Cribrononion subincertum,and Assemblages 4 is Rotalinoides compressiuscula-Elphidium advenum-Ammo-nia ketienziensis.We found that the environmental factors on the foraminiferal distribution in the study area in-cluded sea temperature,salinity,depth,grain size,coastal current and the North Yellow Sea Cold Water Mass.关键词
