摘　　要：【目的】探究甘肃插岗梁自然保护区领春木的群落特征及物种多样性,以期为领春木的保护、开发应用提供科学依据。【方法】采用样方调查法,设置8块样方,分析插岗梁自然保护区领春木群落的物种组成、生活型、区系特征,并对群落物种多样性进行评价。【结果】结果表明,甘肃插岗梁保护区领春木群落中有种子植物35科58属66种,从属的区系分布看,该区域植物区系属北温带分布。在生活型方面,领春木群落中小高位芽和矮高位芽植物占主要组成,在领春木群落物种多样性中,乔木层的Shannon-Wiener指数和Pielou指数分别为5.28和1.71,均高于灌木层和草本层。【结论】插岗梁自然保护区领春木群落植物组成复杂,群落领春木优势度不明显,生境易受人类活动干扰,建议在保护现有领春木群落的同时,对领春木种群特征进行研究,在插岗梁自然保护区开启领春木仿野生栽培研究,合理开发利用野生的领春木资源。【Objective】To examine the community characteristics and species diversity of Euptelea pleiosperma in Chagangliang Nature Reserve,Gansu province,in order to provide scientific basis for the protection,development and application of Euptelea pleiosperma.【Method】The species composition,life form,and flora of Euptelea pleiosperma community in Chagangliang Nature Reserve were analyzed using the 8 quadrat survey method.Additionally,the species diversity of the community was evaluated.【Result】The result indicated that there were 35 families,58 genera and 66 species of seed plants in the Euptelea pleiosperma community in Chagangliang Nature Reserve,Gansu province.According to the subfloristic distribution,the flora in this area was distributed in the north temperate zone.In terms of life forms,mesophanerophyte,microphanerophyte and nanophanerophyte plants were the main components of the community.The Shannon-Wiener index and Pielou index were calculated for the tree layer,the shrub layer,and the herbaceous layer.The tree layer had a Shannon-Wiener index of 5.28 and a Pielou index of 1.71,which were higher than those of the shrub layer and the herbaceous layer.【Conclusion】The plant composition of the community is complex,the dominance of the community is not obvious,and the habitat is easily disturbed by human activities.It is suggested that while protecting the existing community,the population characteristics of the community should be studied,and the research on the imitation-like wild culture of the community should be started in the Chagangliang Nature Reserve,so as to rationally develop and utilize the wild resources of the community.
