摘　　要：为评估广东象头山国家级自然保护区内底栖生物的多样性,并探讨其在生态系统中的作用。通过在不同季节对保护区内的15个点位进行4次调查,共记录到底栖生物1038个,隶属于3门6纲17目49科96种。研究结果表明:该保护区具有丰富的底栖生物多样性,其中节肢动物门物种最为丰富,占总种类数的83.33%。此外,评估了生物密度、丰富度指数(d_(M))和Shannon-Wiener指数(H'),以量化生物多样性水平,并提出了相应的保护建议。This study aims to assess the diversity of benthic organisms in Xiangtoushan National Nature Reserve,Guangdong Province and explore their role in ecosystems.Through four surveys conducted at 15 sites within the protected area in different seasons,a total of 1038 species of benthic organisms were recorded,belonging to 96 families,49 orders,and 6 classes.The results of the study showed that the reserve has a rich diversity of benthic organisms,with arthropods being the most abundant group,accounting for 83.33%of the total species count.In addition,this study also evaluated the biological density,richness index(d_(M)),and Shannon-Wiener index(H'),to quantify the level of biodiversity,and made corresponding conservation recommendations.

关 键 词：底栖生物多样性 生物密度 丰富度指数 象头山国家级自然保护区
