| 为了解海南东寨港红树林区节肢动物多样性水平, 作者于2009 年12 月、2010 年3 月和7 月,对海南东寨港红树林区8 个采样点进行节肢动物群落调查, 共获得底栖节肢动物34 种, 隶属2 纲14科; 方蟹科和沙蟹科是主要类群, 其中双齿近相手蟹(Perisesarma bidens)、原足虫(Kalliapseudes tomiokaensis)和锯眼泥蟹(Ilyoplax serrata)为优势种; 不同潮滩间节肢动物的栖息密度差异不显著, 但生物量差异显著; 不同季节间节肢动物的栖息密度和生物量差异显著; 物种种数S、Margalef 丰富度指数d、Shannon-Wiener 物种多样性指数H′和Pielou 均匀性指数J 皆表现为冬季<春季<夏季。 |

| Abstract: |
| The benthic arthropod communities at eight sampling spots in mangrove area of Dongzhaigang, Hainan were investigated, in December 2009, March 2010 and July 2010, to evaluate the diversity of benthic arthropod. Totally thirty-four species were identified, which belong to 14 families in 2 classes, with Grapsidae and Ocypodidae were the most abundant groups, and Perisesarma bidens, Kalliapseudes tomiokaensis, and Ilyoplax serrata were dominant species. The difference of Arthropod densities among different intertidal levels was not significant, while the difference of biomasses among different intertidal levels was significant. Significant differences were observed among seasons for both densities and biomasses. Number of species, Margalef richness index d, Shannon-Wiener diversity index H′ and Pielou evenness index J all showed such a trend: winter
