摘　　要：2005～2007年分别对南京将军山、紫金山、老山地区蜻蜓资源的种群结构及多样性进行了比较研究,初步确定共有蜻蜓目昆虫43种,隶属于8科28属;分析了3个样地蜻蜓的物种丰富度、相似性指数和多样性指数。蜻蜓物种丰富度由大到小顺序为老山、紫金山、将军山;各样地多样性指数由大到小顺序为老山、紫金山、将军山;将军山与紫金山相似性系数最大,老山与将军山相似性系数最小。Based on the investigation of the fauna and diversity of dragonflies in Jiangjun mountain,Zijin mountain,Lao mountain area of Nanjing City in 20052007,the specimen of the certain quantity was collected and a total of 43 species of Odonata were identified.All the species were belonged to 28 genus,8 families.Species richness,species composition similarity and species diversity index for the three habitats were calculated.The results showed that the species richness sequence was Lao mountain/Zijin mountain 〉Jiangjun mountain;the species diversity decreased in a different sequence was Lao mountain〉 Zijin mountain 〉Jiangjun mountain.The dragonfly species composition of Jiangjun mountain and Zijin mountain had the highest similarity,and the species composition of Lao mountain and Jiangjun mountain had the lowest similarity.
