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 frigida-Cribrononion subincertum, and Assemblages 4 is Rotalinoides compressiuscula-Elphidium advenum-Ammonia ketienziensis. We found that the environmental factors on the foraminiferal distribution in the study area included sea temperature, salinity, depth, grain size, coastal current and the North Yellow Sea Cold Water Mass.
