摘　　要：根据"908专项"海岛海岸带调查工作所获取的资料,江苏省海岛为32个,其中有居民海岛5个,海岛面积为59km2,海岛岸线长度为94.3km。海岛潮间带面积9.2km2,岩滩、砾石滩、砂质滩和淤泥质滩均有。单因子污染指数法环境评价结果表明:海岛潮间带沉积物环境质量好,符合海洋沉积物一类标准要求。海岛潮间带大型底栖生物有138种,生物平均栖息密度高达14 406ind/m2。海岛植被面积总计3 769hm2,其中面积百分比前三位的植被类型为人工植被、水生植被和草丛。According to the data acquired from the island-coastal zone investigation of ＂908 special project＂, there are 32 islands with a total area of 59 km2 and a total coastline length of 94.3 km, 5 out of which are inhabited by people. The intertidal zone area of islands is 9.2 km2 , with 4 kinds of beaches of rocky beach, gravel beach, sandy beach and muddy beach. Environmental assessment results by the single factor pollution index method show that the environmental quality of sediment in the intertidal zone of islands meets the standard for marine sediment quality of first category. There are 138 species of large benthic aquatic animal in the intertidal zone of islands, and Whose average inhabit density reaches 14 406 ind/m~. The total area of island vegetation is 3 769 hm2 , of which the largest three types are artificial vegetation, aquatic vegetation and grass in a descending order.
