摘　　要：为了解大鹏半岛附近海域的渔业资源的空间分布和群落结构特征,2020年春季对深圳大鹏半岛附近海域开展渔业资源调查。该调查对渔业资源密度空间分布情况进行分析,并利用多元统计方法对该海域春季渔业资源群落进行了划分,比较了各群落的生物多样性、均匀度及优势种等结构特征。研究发现,大鹏半岛西侧海域渔业资源密度略高于大鹏半岛东侧海域,大鹏半岛东南侧海域为东西侧海域春季渔业资源密度变化的过渡带,呈现出由西南向东北逐渐减小的趋势。大鹏半岛附近海域渔业资源量历年来呈现下降趋势,2020年春季的调查结果显示,其中位于西侧和南侧海域的群落(Group1)资源密度最高,为553.59 kg·km^(-2);位于东侧(Group 2)和东北侧(Group 3)的群落资源密度相近,分别为278.61 kg·km^(-2)和273.33 kg·km^(-2);均较低。总体看来,大鹏半岛海域渔业资源逐渐衰退,优势种演替,应针对各群落特点及受人类活动影响程度进行生态修复。该研究结果可为大鹏半岛渔业资源的保护和管理提供参考。Based on the 2020 fishery resources survey data in spring in coastal waters of Dapeng Peninsula,Shenzhen,the spatial distribution and community structure were studied.To compare the biodiversity,evenness,dominant species and other structure characteristics of various communities,the spatial distribution of the fishery resources density in this area were analyzed while the communities were classified using multivariate statistical method.The fishery resources density on the west of Dapeng Peninsula was higher than the east,and the fishery resources density on the southeast gradually decreased from southwest to northeast in this area as a density transition zone between the east and west of Dapeng Peninsula.The fishery resources in coastal waters of this area had decreased over the years,which could be divided into three parts.The western and southern community's resource density was the highest,which was 553.59 kg·km^(-2),while the eastern and the northeastern community's resource density were equal with a lower level,which were 278.61kg·km^(-2) and 273.33 kg·km^(-2).In general,the fishery resources in coastal waters of Dapeng Peninsula gradually decreased,while the dominant species were changed.Therefore,ecological restoration should be carried out according to the characteristics of each community and the human impact.The results of this paper may give a clue for the protection and management of fishery resources in coastal waters of Dapeng Peninsula.
