中文摘要：潮间带是海陆生态系统的过渡地带,对人类活动干扰较为敏感。为探究不同人类活动下北部湾江山半岛潮间带大型底栖动物多样性,并揭示其底栖生态质量,于2023年秋季(11月)和2024年春季(4月)分别对江山半岛白龙尾和白浪滩2个潮间带断面开展了大型底栖动物调查,分析其种类组成、栖息密度、生物量、优势种及生物多样性,并用海洋生物指数(AZTI Marine Biotic Index,AMBI)和多变量海洋生物指数(M-AMBI)对生态质量进行了评估。结果显示,共采集到大型底栖动物87种,其中软体动物41种,环节动物21种和节肢动物19种,其他类群动物6种;春季大型底栖动物的平均栖息密度、生物量和香农多样性指数均低于秋季;相对重要性指数(Index of Relative Importance,IRI)结果显示,2个断面优势种存在明显的季节更替且无共有优势种。AMBI和M-AMBI评估结果表明,虽然白龙尾断面受到的扰动整体略高于白浪滩断面,但总体而言,2个断面的生态质量均处于良好水平。

外文摘要：Intertidal zone is a transitional zone between marine and terrestrial ecosystems,which is sensitive to human activities.To explore the diversity of macrobenthos in the intertidal zone of Jiangshan Peninsula under different disturbances of human activity and evaluate its benthic ecological quality,we carried out a survey on macrobenthos in November 2023(Autumn)and April 2024(Spring)in two intertidal transects(Bailongwei and Bailangtan)in Jiangshan Peninsula,Beibu Gulf.We analyzed the species composition,density,biomass,dominant species and biodiversity of macrobenthos,and evaluated the ecological quality status of these two intertidal transects by using the AZTI Marine Biotic Index(AMBI)and multivariate AMBI(M-AMBI).The results showed that a total of 87 taxa of macrobenthos were collected,among which Mollusks were the most abundant(41 species),followed by Annelida(21 species),Arthropoda(19 species),and other groups(Six species).The average density,biomass and Shannon diversity index of macrobenthos in spring were lower than those in autumn.The results of the relative importance index(IRI)indicate that there was an obvious change in the dominant species of macrobenthos in the two intertidal transects across the season.The results of the AMBI and M-AMBI indexes show that although the disturbance at the Bailongwei transect is slightly higher than that at the Bailangtan transect,the overall ecological quality of both transects is generally at a good level.
