| 摘 要： | 文章根据2020年7月的调查数据，研究山口红树林保护区潮间带大型底栖动物群落的分布特征和物种多样性。结果表明：本次调查共记录潮间带大型底栖动物7门9纲52种，以节肢动物和软体动物为主，优势种包括隆背张口蟹（Chasmagnathus convexus）、扁平拟闭口蟹（Paracleistostoma depressum）、红树蚬（Gelonia coaxans）等10种；大型底栖动物群落的平均生物量和平均密度分别为81.17 g/m2和54 ind/m2，其中节肢动物占比分别为43.70%和80.09%，节肢动物对群落密度作出的贡献最大；大型底栖动物群落的多样性指数为0.86～2.52，系统聚类和多维尺度分析可将群落划分为3个类型；与我国其他红树林区相比，山口红树林保护区潮间带大型底栖动物群落的物种多样性水平较低。

| Abstract: | Based on the survey data in July 2020, the paper investigated the distribution characteristics and species diversity of the intertidal macrobenthic community in the Shankou Mangrove Reserve. A total of 52 species of macrobenthic animals in 7 phyla and 9 orders were recorded in this survey, mainly arthropods and mollusks. Chasmagnathus convexus, Paracleistostoma depressum, Gelonia coaxans, etc. were ranked as the top ten dominant species in the area. The average biomass and average density of macrobenthos were 81.17 g/m2 and 54 ind/m2, with Arthropods accounting for 43.70% and 80.09% of the total. Arthropods contributed the most to the community density. The diversity index of the macrobenthic community ranged from 0.86 to 2.52. Cluster analysis and multidimensional scale analysis could classify the communities into 3 types. Species diversity levels of the intertidal macrobenthic community in the Shankou Mangrove Reserve were low compared with other mangrove areas in China. |
