| 为研究福建海岛水域软体动物多样性与分布，根据1990年2月至1992年1月对福建乡级以上海岛水域进行的大型底栖生物调查资料进行了深入分析。结果表明，福建海岛水域软体动物有82科97属345种,主要有蚶科(Arcidae)、贻贝科(Mytilidae)、蛤蜊科(Mactridae)、樱蛤科(Tellinidae)、帘蛤科(Veneridae)、篮蛤科(Corbulidae)、角贝科(Dentaliidae)、玉螺科(Naticidae)、骨螺科(Muricidae)、蛾螺科(Buccinidae)、织纹螺科(Nassariidae)、衲螺科(Cancellariidae)、塔螺科(Turridae)、笋螺科(Terebridae)、小塔螺科(Pyramidellidae)等。在12个乡级以上海岛水域，福建中南部岛屿水域软体动物物种数较多，北部相对较少。平均生物量为8.81 g/m2，栖息密度为36个/m2。生物量厦门岛水域最高（33.18 g/m2），南日岛最低（0.73 g/m2）；栖息密度江阴岛最高（188个/m2），湄洲岛最低（4个/m2）。福建省海岛水域软体动物种数季节变化，夏季大于冬季大于秋季大于春季；数量季节变化，生物量以春季最高，冬季最低；栖息密度以春季最高，秋季最低。

| Abstract: |
| In order to analyze the diversity and distribution of mollusca around the waters of islands, Fujian Province, we conducted a large-scale survey of bottom-dwelling organisms from February 1990 to January 1992 on an island in Fujian over the waters of the township. The results showed that there are 82 families, 96 genua, 345 specise of mollusc around the waters of islands, Fujian Province, and the mainly families are as follows: Arcidae, Mytilidae, Mactridae, Tellinidae, Veneridae, Corbulidae, Dentaliidae, Naticidae, Muricidae, Buccinidae, Nassariidae, Cancellariidae, Turridae, Terebridae, Pyramidellidae. In the 12 waters of islands, the species of mollusc located more around south-central islands than that around the northern islands. The average biomass of mollusca is 8.81 g/m2, the density is 36 ind./m2 around the waters of islands, Fujian Province. The biomass of waters around Xiamen island is the highest (33.18 g/m2), that of in Nanri island is the lowest (0.73 g/m2); The density of waters around Jiangyin island is the highest (188 ind./m2), that of in Meizhou island the lowest (4 ind./m2). The seasonal variation of mollusc species around the waters of islands, Fujian Province is that the species number is more in the summer than in winter, it is more in the winter than in autumn, and it is more in the autumn than in spring. The biomass is the highest in spring, and the lowest in winter; the highest density is in spring and lowest in autumn.
