摘　　要：大亚湾海域是粤港澳大湾区生态安全屏障的重要区域。2020年6~7月,国内首次发生大亚湾海域“尖笔帽螺”生物灾害事件。本文利用尖笔帽螺持续跟踪监测数据,分析了尖笔帽螺生物性状、时空变异特征,探讨了生境与生物量分布的关系,结果显示:1) 尖笔帽螺的生物性状显示其为南海海域常见物种;2)尖笔帽螺的生物量和密度在7月8日~7月10日达到最大值,主要分布在大亚湾中西部海域;3) 尖笔帽螺的活动受到海水溶解氧的显著影响;4) 尖笔帽螺异常增殖需进一步研究其生态位特征。The Daya Bay area is an important siteof the ecological security barrier of the Guangdong-Hong Kong-Macao Greater BayArea. The first biological disaster event of Creseis acicula occurred from June to July 2020 in Daya Bay ofChina. Using the continuous monitoring data, we analyzed the biologicalcharacteristics, temporal and spatial variation characteristics of Creseis acicula. Furthermore, wediscussed the relationship between living habitat and biomass distribution. Resultsshow that: 1) The biological characteristics of Creseis acicula suggest it is a common species in South China Sea;2) The biomass and number of Creseisacicula reached the maximum from July 8 to July 10, with the distributionmainly in the central and western of Daya Bay;3) The dissolved oxygen inseawater affected the activity of Creseisacicula significantly;4) It is necessary to study the nichecharacteristics for the anomalous proliferation of Creseis acicula.
