摘　　要：2010年—2011年对安徽鹞落坪自然保护区的蜻蜓目昆虫区系及多样性进行了抽样调查研究。通过标本采集、制作和鉴定,分析了该地区蜻蜓目昆虫的区系特点、多样性指数、优势度指数和均匀度系数。共采集蜻蜓标本18941号,12科53种,其中以蜻科Liberllulidea最多共13属26种,优势种为黄蜻Pantala flavesens flavesens Fabricius。区系分析结果支持研究地属于东洋界和古北交界过渡地带。结合不同生境物种数、多样性和均匀度分析,研究结果表明蜻蜓分布受环境中水域和植被的分布特点影响。研究结果还表明蜻蜓物种数、多样性指数、均匀度指数随着海拔的升高而降低。与周边地区蜻蜓研究的相关结果对比,鹞落坪地区蜻蜓具有物种数多,多样性、均匀度偏低的特点。The odonata in Yaoluoping Nature Reserve was investigated in 2010 -2011. According to the collections, productions and i- dentifications of the specimens, it was preliminarily confirmed that from 18941 specimens there were 12 families, 53 species of odonata in Yaoluoping reserve in which there were 13 genus, 26 species of LibeUulidae and Pantalaflavescens fabricius was the most dominant specie. The floristic analysis suggested Yaoluoping reserve is the transition zone between palaearetic and oriental region. It was found that the distribution of odonata was influenced by the water and characteristic of vegetations. The species numbers, dominance and evenness index decreased with the altitude.
