| 为了解瓯江口树排沙湿地不同生境大型底栖动物群落多样性, 于2014年10月至2015年6月对红树林、互花米草及光滩3种生境开展大型底栖动物调查。共鉴定出大型底栖动物48种, 隶属于5纲15目31科40属。大型底栖动物年平均栖息密度和生物量, 红树林生境最高, 互花米草生境次之, 光滩生境最低。采用物种多样性指数和G-F多样性指数分析不同生境大型底栖动物群落多样性, 发现红树林生境大型底栖动物的多样性高于互花米草生境和光滩生境。单因素方差分析表明: 物种数、栖息密度、生物量及物种多样性季节间差异不显著, 而物种数、Shannon-Wiener多样性指数与Margalef物种丰富度指数生境间差异显著。人工恢复红树林有助于提高大型底栖动物群落的多样性。 |

| Abstract: |
| We investigated the community diversity of macrobenthos in different habitats of Shupaisha Wetland in Oujiang River estuary in three habitat forms, i.e., mangrove habitat, Spartina alterniflora habitat, and naked beach habitat from October 2014 to June 2015. In total, 48 species were recorded, belonging to 40 genus, 31 families, 15 classes, and 5 phyla. The average inhabitant density and biomass were the highest in mangrove habitat, followed by S. alterniflora habitat and naked beach habitat. In addition, we studied the community diversity of macrobenthos in different habitats using species diversity index and G-F diversity. The mangrove habitat showed higher diversity than those of the other habitats. One-way ANOVA analysis revealed no significant difference in season in species number, inhabitant density, biomass, and species diversity, but in habitat in species number, Shannon-Wiener index, and Margalef species richness. Authors believe that artificial restoration of mangrove will enhance the diversity of macrobenthos community. |
