摘　　要：为明确井冈山自然保护区蜻蜓目昆虫种质资源和群落特征,为蜻蜓目昆虫资源的保护和合理利用提供理论依据,2018-2021年在井冈山自然保护区选取长古岭(海拔470 m左右)、大井(海拔930 m左右)、黄洋界(海拔1200 m左右)3个不同海拔样地开展蜻蜓资源调查。采用Simpson优势集中性指数、Pielon均匀度指数、Berger-Parker优势度指数和ShannonWiener多样性指数对3个样地的蜻蜓进行多样性分析。共采集到标本483只,隶属于2亚目8科16属23种,其中蜻科(Libellulidae)占据绝对优势,属数和种数分别占总数的37.50%和56.52%;大井和黄洋界的群落结构指标均无显著差异(P>0.05),大井和黄洋界的多样性指数、均匀度指数均显著高于长古岭(P<0.05),而优势度指数、优势集中性指数则显著低于长古岭(P<0.05)。结果表明井冈山自然保护区内海拔较低的长古岭蜻蜓目昆虫群落的多样性较低,但优势种的地位更为突出。In order to clarify the species resources and community characteristics of Odonata insects in Jinggangshan Nature Reserve,and provide a theoretical basis for the protection and rational utilization of Odonata resources,dragonfly resources were investigated in Changguling(470 m above sea level),Dajing(930 m above sea level)and Huangyangjie(1200 m above sea level)of Jinggangshan from 2018 to 2021.Shannon-Wiener diversity index,Pielon evenness index,Berger-Parker dominance index and Simpson dominance concentration index were used to analyze the diversity of dragonflies in three sampling sites.A total of 483 specimens were collected and identified,belonging to 23 species,16 genera,8families,2 suborders.Among them,Libellulidae occupied an absolute advantage,and the numbers of genera and species accounted for 37.50%and 56.52%of the total,respectively.There was no significant difference in community structure index between Dajing and Huangyangjie(P>0.05).The diversity index and evenness index of Dajing and Huangyangjie were significantly higher than those of Changguling(P<0.05),while the dominance index and dominance concentration index were significantly lower than those of Changguling(P<0.05).This indicates that the diversity of Odonata community is low in Changguling,which is at a lower altitude in Jinggangshan Nature Reserve,but the dominant species are more prominent.
