摘　　要：利用2017年至2021年昌黎黄金海岸国家级自然保护区调查数据,分析了近年来研究区域海水环境及文昌鱼栖息密度和生物量的变化情况,运用统计分析法,分析了文昌鱼栖息密度、生物量和海水环境因子的相关性。结果表明:文昌鱼栖息密度、生物量和p H呈负的弱相关性,文昌鱼栖息密度、生物量和氨氮、硅酸盐浓度呈弱相关性,和盐度、水温、溶解氧、化学需氧量、亚硝酸盐、硝酸盐、活性磷酸盐浓度呈极弱相关性或者无相关性。This paper uses the survey data of Changli Gold Coast National Nature Reserve from 2017 to 2021 to analyze the changes in the seawater environment and the habitat density and biomass of Amphioxus in the study area in recent years.Analyze correlations between density,biomass and marine environmental factors in statistical analysis. The results show that the habitat density,biomass of Amphioxus and p H,ammonia nitrogen,silicate concentrations were weakly correlated,and Shows very weak or no correlation to salinity,water temperature,dissolved oxygen,chemical oxygen demand,nitrite,nitrate,and active phosphate concentrations.
