| 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。

| Abstract: | 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. |
