底栖动物在红树林区的分布不仅限于林下,通常许多软体动物还能附着或固着于红树植物的茎、叶等地上部分．2006年11月至2007年7月共四个季度对同安湾两片人工种植红树林进行了树上底栖动物的定量调查,共获得底栖动物8种,分别隶属于软体动物门2纲6科和节肢动物门甲壳纲,均属暖水性种类．凤林树上大型底栖动物年平均密度为10．74 ind·m－2,生物量为2．89 g·m－2．优势种为黑口滨螺和粗糙滨螺,前者主要分布在树干和较粗的枝条上且其密度在向海林缘达到最大,后者是唯一在6个采样点均能采到的广分布种．山后亭树上大型底栖动物年平均密度和生物量分别为586．51 ind·m－2和113．37g·m－2,优势种代表为角巨牡蛎和白脊藤壶,主要分布在红树主干和枝条上．

Macrofaunal distribution at the mangrove forest is not limited to forests,many species of fau-na would distribute on the above-ground plant parts by adhesion or sessile on stems,leaves,etc.The distribution of plant-dwelling fauna was investigated seasonally from November 2006 to July 2007,in Tong’an Bay mangrove area.Eight species in 2 classes of 6 families were identified.At the Fenglin mangrove area,the average density and biomass of plant-dwelling fauna were 10.74 ind·m-2 and 2.89 g·m-2 ,respectively.The dominant species were Littoraia melanostoma and Littorinopsis interme-dia.The former species usually distributed on the trunks or branches and the latter was the only spe-cies which can be found at all the six stations.At the Shanhouting mangrove area,the average density and biomass of plant-dwelling fauna were 586.51 ind·m-2 and 113.37 g·m-2 ,respectively.And the dominant species were Crassostrea angulata and Balanus albicostatus,which both preferred to twine around the branches of the trees.
