摘要:

为了解广西北海红树林宜林滩涂大型底栖动物群落特征, 本文首次在北海市选择了2条光滩断面、2条有少量互花米草分布的断面和2条被互花米草覆盖的断面开展生态调查, 调查了大型底栖动物的群落结构特征, 并分析了其与环境因子之间的关系。结果表明, 调查区域大型底栖动物共29种, 不同生境的软体动物生物量、节肢动物栖息密度及蟹洞数量差异显著(P< 0.05), 大型底栖动物的种类组成与沉积物的偏态显著正相关(P< 0.05)。光滩样地黄金村HJ群落结构稳定, 其余样地大型底栖动物的群落结构均不稳定。互花米草的生长会对大型底栖动物群落结构产生影响。

Abstract:

In order to understand the characteristics of macrobenthic communities in the intertidal zone for mangroves, two sections of bare flat, two sections with a small number of Spartina alterniflora distribution and two sections covered by Spartina alterniflora were selected in Beihai for ecological investigation, and the community structure of macrobenthic animals and its relationship with environmental factors were analyzed. There were 29 macrobenthic species in the survey area, and there were significant differences in mollusc biomass, arthropod habitat density and crab burrow number in different habitats (P< 0.05), and the species composition of macrobenthic animals was positively correlated with sediment skewness (P< 0.05). The HJ community structure was stable in the bare flat, but the community structure of macrobenthic animals in the other plots was unstable. The growth of Spartina alterniflora affects the structure of macrobenthic communities.

Key words: macrobenthic animals, community structure, Spartina alterniflora, mangrove
