摘　　要：[目的]对保护、利用蜻蜓目昆虫提供一定的参考。[方法]在2007～2009年春夏蜻蜓羽化的高峰期,随机采集蜻蜓目昆虫,并分类鉴定。[结果]初步确定徐州地区蜻蜓目昆虫共计21种,隶属于5科、17属。[结论]徐州地区的蜻蜓广布种稍占优势,有7种,占总数的33.33%;古北界的种类相对较少,有2种,约占总数的9.5%。物种多样性指数为2.2999,优势度指数为0.0952,均匀度指数为0.7554。[Objective] The research aimed to provide reference for the protection and utilization of odonata insects. [Method] At the fastigium of dragonflies eclosion in spring and summer of 2007-2009,odonata insects were grabed randomly and classified,appraised. [Result] Odonata insects in Xuzhou area were determined initially,which was summed to 21 kinds,subordinate in 5 branches,17 genuses. [Conclusion] Widespread species had slight superiority,which was 7 kinds,accounted for 33.33%. Gubei district＇s type was relatively few,which was 2 kinds,approximately accounted for 9.5%. The region＇s diversity index for the dragonflies was 2.299 9,index for dominance of 0.095 2,the index for uniformity of 0.755 4.
