摘　　要：为明确山西太行山蝽类昆虫的物种多样性和分布特点,分别于2022年和2023年的6-9月在该地区开展蝽类昆虫多样性调查和垂直分布分析。结果表明,2022年和2023年6-9月共采集到蝽类昆虫6 103头,隶属于25科41亚科110属共计189种。不同海拔梯度下的蝽类昆虫优势类群不同,海拔段Ⅱ(770~1 140 m)、海拔段Ⅲ(1140~1510 m)、海拔段Ⅴ(1880~2250 m)的优势类群均为盲蝽科,海拔段Ⅰ(400~770 m)的优势类群是蝽科,海拔段Ⅳ(1510~1880 m)的优势类群是龟蝽科;海拔对山西太行山蝽类昆虫物种个体数、物种数、Shannon-Wiener多样性指数、Pielou均匀度指数有显著影响,对Margalef丰富度指数和Simpson优势度指数无显著影响;不同海拔间蝽类昆虫物种组成相似性较低,相似性系数为0.0408~0.1475,以海拔段Ⅱ和海拔段Ⅲ蝽类昆虫较为相似;对山西太行山蝽类昆虫物种数影响最大的环境因子为采集地最热季度的降水量(BIO18),相关系数为0.238(P<0.05),对山西太行山蝽类昆虫个体数影响最大的环境因子为采集地的年降水量(BIO12),相关系数为0.263(P<0.05)。综上,山西太行山地区生态环境多样,蝽类昆虫资源丰富,低海拔和高海拔区间蝽类昆虫物种丰富度较低,中海拔区间的蝽类昆虫物种丰富,垂直分布格局为单峰格局。In order to clarify the species diversity and distribution characteristics of true bugs in Taihang Mountains,Shanxi Province,a survey of true bugs diversity was conducted from June to September in 2022 and 2023,and vertical distribution at five different altitudes was analyzed in this area.The results of biodiversity analysis showed that a total of 6103 true bugs were collected from June to September in 2022 and 2023,belonging to 25 families,41 subfamilies,110 genera,a total of 189 species.The dominant groups under different altitude gradients were different.The dominant group in altitudeⅡ(770—1140 m),altitudeⅢ(1140—1510 m),and altitudeⅤ(1880—2250 m)was Miridae.The dominant group at altitudeⅠ(400—770 m)was Pentatomidae,and the dominant group at altitudeⅣ(1510—1880 m)was Plataspidae.The altitude had significant effects on the individual number,species number,Shannon-Wiener diversity index and Pielou evenness index,but had no significant effects on Margalef richness index and Simpson dominance index.The species composition of true bugs community at different altitudes was less similar,and the species similarity coefficient was ranging from 0.0408 to 0.1475,the true bug community at altitudeⅡand altitudeⅢwas more similar.The environmental factor that had the greatest influence on the species number of true bugs in Taihang Mountains of Shanxi Province was the precipitation in the hottest quarter of the collection site(BIO18),and the correlation coefficient was 0.238(P<0.05).The environmental factor that had the greatest influence on the individual number of true bugs in Taihang Mountains of Shanxi Province was the annual precipitation(BIO12),and the correlation coefficient was 0.263(P<0.05).In summary,the ecological environment of Taihang Mountains in Shanxi Province is diverse,and the resources of true bugs species are abundant.In this area,the species richness of true bugs in low and high altitudes is relatively smaller,while the species in middle altitudes are abundant,and the vertical dist
