摘要
对牛背梁自然保护区的秦岭梁、南坡的北沟、北坡的石砭峪进行了昆虫多样性调查。共采集到昆虫标本3 053号,隶属14目、98科、442种;优势类群双翅目、鞘翅目、半翅目、同翅目、膜翅目的科数分别占总数的22.45%、18%、12%、11%和11%,其种类数分别占27.38%、18.55%、16.74%、13.12%和12.9%。物种丰富度指数为秦岭梁(42.284 0)>北沟(24.464 6)>北石砭峪(21.229 6),多样性指数为北沟(4.469 5)>石砭峪(4.427 7)>秦岭梁(3.580 3),其中,随海拔的升高,秦岭梁昆虫物种的丰富度指数和多样性指数呈先升高后降低的趋势。
In order to understand the insect diversity in herbaceous layers in Niubeiliang National Nature Reserve,an investigation was carried out in three areas within the reserve：Qinlingliang,Beigou,and Shibianyu.A total of 3 053 specimens were identified,accounting for 442 species,98 families and 14 orders.The dominant groups were Diptera,Coleoptera,Hemiptera,Homoptera and Hymenoptera,accounting for 22.45%,18%,12%,11% and 11%,respectively of the total number of families,and 27.38%,18.55%,16.74%,13.12% and 12.9%,respectively of the total number of species.The species richness index of the 3 habitats were in the order of Qinlingliang（42.284 0）Beigou（24.464 6）Shibianyu（21.229 6）,the diversity index were in the order of Beigou（4.4695）shibianyu（4.427 7）Qinlingliang（3.580 3）.In addition,the species richness index and diversity index of Qinlingliang increased first and then fall with the increase of elevation.
