摘　　要：为深入探究环境因子与渤海强壮滨箭虫四季种群结构动态的关系,并进一步丰富近年来渤海海域浮游动物的相关研究,本研究于2018年4月—2019年12月在渤海海区开展4个航次的海洋综合调查工作,对渤海强壮滨箭虫的时空分布以及生长繁殖状况进行了研究,并讨论了温度、盐度、深度以及饵料等环境因子对其种群结构产生的影响。研究结果显示:盐度与强壮滨箭虫的时空分布具有显著的相关性,在28.5~32.7的范围内,盐度的升高对强壮滨箭虫种群增长有抑制作用;温度通过影响强壮滨箭虫的摄食、代谢来影响其季节上的变化;桡足类作为强壮滨箭虫的主要饵料,也是影响强壮滨箭虫生长繁殖的重要因素。In order to better understand the relationship between environmental factors and the structure dynamics of the four-season population of Aidanosagitta crassa in the Bohai Sea,and also to enrich the relevant studies of zooplankton in the Bohai sea in recent years,from April 2018 to December 2019,four voyages of comprehensive marine survey were conducted in the Bohai Sea.Aiming to study the spatial and temporal distribution,aggregation intensity,and growth and reproduction of A.crassa in the Bohai Sea,and to discuss how various environmental factors affect its population structure.The abundance of A.crassa in the Bohai Sea is summer>spring>autumn>winter in all seasons,with higher abundance in the nearshore and lower abundance in the middle of the sea area,and it is in a state of aggregated distribution in all seasons.Among the environmental factors studied,salinity was significantly correlated with the spatial and temporal distribution of A.crassa,and in the range of 28.5 to 32.7,an increase in salinity had an inhibitory effect on the population growth of A.crassa.Temperature influences the seasonal variation of A.crassa by affecting their intrinsic factors such as feeding and metabolism.Copepods serve as the main bait for A.crassa and are an important factor in the growth and reproduction of A.crassa.
