摘要:

记录到海南东寨港红树林滩涂大型底栖动物68种,其中软体动物39种,占记录到物种数的57.4%;甲壳动物19种,占记录到物种数的27.9%。冬季优势种是珠带拟蟹手螺(Cerithidea cingulata )、古氏滩栖螺(Batillaria cumingi )和环肋樱蛤(Cyclotellina remies );夏季优势种是珠带拟蟹手螺、环肋樱蛤和红肉河蓝蛤(Potamocorbula rubromuscula )。大型底栖动物的生物量夏季平均为133.0 g/m2,冬季平均为63.0 g/m2; 栖息密度夏季平均为106.4 个/m2,冬季平均为103.5 个/m2。以密度为计量单位的物种多样性指数夏季为1.841,冬季为0.380,均匀度指数夏季为0.514,冬季为0.112;以生物量为计量单位的物种多样性指数夏季为1.994,冬季为1.751, 均匀度指数夏季为0.556,冬季为0.520。大型底栖动物的生物量、栖息密度、物种多样性指数和均匀度指数大都有季节变化及底质差异,基本趋势是夏季明显高于冬季,沙泥底的滩涂高于泥底质的滩涂。

AbstractThis paper reported the results of investigation on benthic macrofauna on mud flat in Dongzhaigang Mangrove Reserve , Hainan. Sixty eight species of benthic macrofauna , belonging to six Phyla , 34 families were found. The dominant species were Cerithidea cingulata , Batillaria cumingi , Cyclotellina remies and Potamocorbula rubromuscula of Mollusca. The mean biomass of benthic macrofaunu in summer and in winter was 133.0 g/m2 and 63.0 g/m2 , respectively. The mean densities were 106.4 ind./m2 in summer and 103. 5 ind./m2 in winter. The species diversity indexes of benthic macrofaunu in summer and in winter were 1.841 and 0.380 , respectively. The species evenness indexes were 0.514 and 0.113 , respectively. The biomass diversity indexes of benthic macrofaunu were 1.994 in summer and and 1.751 in winter. The biomass evenness indexes were 0.556 and 0.520 , respectively. The biomass , density , species diversity index and biomass diversity index of benthic macrofauna varied with season and substrate. All these values were greater in summer than in winter , greater in sand2mud substrate than in mud substrate
