摘　　要：2008年6月、12月分别对珠江口淇澳岛3种不同生境类型区域(红树林区、基围鱼塘和陆域林地)的昆虫群落进行调查。其昆虫群落由10目、68科组成;个体数量最多的是半翅目,其次为膜翅目、双翅目、鳞翅目和鞘翅目;半翅目昆虫的类群最丰富,其次为膜翅目、鳞翅目和鞘翅目。不同生境类型区域昆虫群落的组成及多样性特征存在差异,基围鱼塘昆虫类群最为丰富,红树林区昆虫类群较少;昆虫群落的个体数量从大到小依次为基围鱼塘、陆域林地和红树林区;红树林区的植被种类和群落结构较为单一,生境相对简单,昆虫群落的丰富度和Shannon-Wiener指数均低于陆域林地和基围鱼塘,优势度远高于基围鱼塘和陆域林地,均匀度大小依次为基围鱼塘﹥陆域林地﹥红树林区。In June and December 2008, two investigations were made on the insect communities in mangrove, surround pond and land forest region in Qi＇ao Island, Zhuhai. 68 families of insects belonging to 10 orders were recorded. Hemiptera had the most abundant individuals, followed by Hymenoptera, Diptera, Lepidoptera and Coleoptera. Hemiptera was the highest in the number of families, followed by Hymenoptera, Lepidoptera and Coleoptera. The quantity and diversity indexes of insect communities varied in different habitats. Both the number of individuals and families were the highest in surround pond and the lowest in mangrove region. Margalef richness, Shannon-Wiener diversity and the evenness index were the lowest in mangrove region. While, mangrove region showed the highest dominance index, followed by land forest and surround pond region.
