摘　　要：作者于2005～2010年对南京将军山地区蜻蜓资源进行了初步的调查,并且采集了一定数量的标本,通过对采集标本的鉴定和分类,初步确定将军山地区蜻蜓目昆虫共计24种,隶属于6科17属.其区系组成的特点是:东洋成分占优势,有15种,约占总数的62.5%;在中国地理分布中明显偏向华中区,在采到的24种标本中华中区占有20种,约占总数的83.33%.蜻蜓的多样性指数为2.9298,均匀度指数为0.9219,优势度指数为0.4486,优势集中性指数为0.0774.From 2005 to 2010, a preliminary investigation of dragonflies was first made in Nanjing Jiangjun Mountain and a certain number of samples were collected. By means of identification and verification, it has been tentatively decided that there are 24 species of odonata in this area, classified into 17 genus, 6 families. The characteristic of the fauna is that Oriental species （ 15species out of 24） account for approximately 62.5 % of the total. In China＇ s geographical distribution, the majority of the species are found in central China （20 species out of 24, accounting for 83.33 % of the total）. The diversity index is 2. 9298; the evenness index, 0.9219; the dominance index, 0. 1698 ; the superior centrality index, 0. 0774.
