摘　　要：于2022年7月,对山西省太行山区和吕梁山区典型灌草生境的昆虫种类进行调查,并开展多样性研究。结果表明,在太行山区灌草生境中共采集到1702头昆虫,隶属于8目40科78种,优势目为直翅目、半翅目和鞘翅目,优势科为叶蝉科、网翅蝗科和剑角蝗科;在吕梁山区灌草生境中共采集到1958头昆虫,隶属于8目36科74种,优势目为直翅目、鞘翅目和半翅目,优势科为网翅蝗科、斑翅蝗科和芫菁科。总体来看,吕梁山区昆虫的Margalef丰富度指数、Shannon-Wiener多样性指数、Pielou均匀度指数较高,表明吕梁山区的昆虫物种丰富,有较为稳定的群落结构。太行山区昆虫的Simpson优势度指数较高,表明太行山区昆虫群落集中性较高,存在明显的优势种群。A survey and analysis of insects in typical shrub and grass habitats in Taihang and Lvliang mountainous areas of Shanxi Province was conducted in July 2022 and the diversity was studied.The results showed that a total of 1702 insects belonging to 8 orders,40 families and 78 species were collected in the shrub-grass habitat in Taihang Mountains area.The dominant orders were Orthoptera,Hemiptera and Coleoptera,while the dominant families were Cicadellidae,Arcypteridae and Acrididae.A total of 1958 insects belonging to 8 orders,36 families and 74 species were collected in the shrub-grass habitat of the Lvliang Mountain area.The dominant orders were Orthoptera,Coleoptera and Hemiptera,while the dominant families were Arcypteridae,Oedipodidae and Meloidae.Overall,the Margalef richness index,Shannon-Wiener diversity index and Pielou evenness index of insects in the Lvliang Mountain area were higher,which indicating that the insect species in the Lvliang Mountain area were abundant and had a relatively stable community structure.The Simpson dominance index of insects in the Taihang Mountains was higher,which indicating a high concentration of insect communities and the existence of obvious dominant populations.
