A total of 433 samples obtained from surface sediments of the Liaodong Bay were analyzed quantitatively. The benthic foraminifera fauna in the studied area was mainly composed of eurythermal-euryhaline and cool-water species.Based on the Q-mode factor analysis, four assemblages are recognized: 1) Elphidium magellanicum-Nonion akitaense-Buccella frigida assemblage; 2) Ammonia beccarii var.-Quinqueloculina akneriana assemblage; 3) Cribrononion vitreum-Buccella frigida-Protelphidium tuberculatum assemblage; and 4) Ammoina annectens-Buccella frigida assemblage. Data suggest that the benthic foraminiferal distribution is closely related to the sedimentary environments under the control of temperature, salinity, sediment type and alongshore currents.
