摘　　要：2005—2006年对广州市全区域的昆虫群落进行6次调查，对该区域昆虫群落结构、多样性及时间动态进行了分析。共记述22个目、216个科。鞘翅目的类群最丰富，双翅目、鳞翅目、膜翅目和半翅目次之；鞘翅目昆虫的个体数量最多（30．45），其次为鳞翅目（18．89）和膜翅目（14．78）。6～7月昆虫类群数和个体数量最多，12月最少；6～7月的种类丰度最高，其次为3～4月、9～10月，12月最低；Shannon—Wiener指数从高到低依次为6～7月、9—10月、3～4月、12月；Pielou均匀度指数从高到低依次为6～7月、9～10月、12月、3～4月；12月的种类优势度最高，其次为3—4月、9～10月，最低为6～7月。The insect community diversity of Guangzhou city was investigated from May 2005 to December 2006. 216 families in 22 orders were recorded. The results showed that Coleoptera had the most .abundant families, followed by Diptera, Lepidoptera, Hymenoptera, Hemiptera; Also, Coleoptera had the most abundant individuals, followed by Lepidoptera and Hymenoptera. Both the number of families and individuals were the highest in June and July and the lowest in December. Margalef species richness and Shannon - Wiener indices were used to analyze the insect community diversity in different month. The results showed that both indices were the highest in June and July and the lowest in December. While, De- cember showed the highest dominance index, followed by March and April, September and October, June and July. June and July were the highest in evenness index, followed by September and October, December, March and April.
