祁连山北坡熊蜂种类及区系研究

A taxonomic study and faunistic distribution of Bombus in the northern slopes of Qilian Mountains

在2004-2007年对祁连山北坡熊蜂种类进行了调查,根据所采集的标本和中国科学院动物研究所馆藏标本,经鉴定该地区有熊蜂14种。另外,对该地区的熊蜂区系成分进行了初步的分析。结果表明,祁连山北坡熊蜂在世界动物地理区系中是以古北界种为主,东洋、古北界共有种为次的种群结构;在中国动物地理区划中有7个分布型,以青藏、蒙新区共有种占首位,单区种仅有蒙新区、青藏区,尤以蒙新区种为最。在跨区种类中,同时跨蒙新区的种类比例很大,为88.89%,其余依次为跨青藏区、西南区、华北区,跨华中、华南区的则较少。

The species of Bombus were studied by a field investigation in the northern slopes of Qilian Mountains during 2004-2007,accordig to the collected samples and specimens in the Institute of Zoology,CAS.Fourteen species of Bombus in the northern slopes of Qilian Mountains were identified.In addition,the fauna of Bombus in studied region was preliminary analysed.The results showed that Bombus in the northern slopes of Qilian Mountains mainly composited of species of the Palaearctic in terms of the world fauna,followed by Oriental and Palaearctic species.Among 7 distribution types of Chinese animals geographical division.Qinghai-Tibet and Mongo-Sinkiang species accounted for the first in the studied region,and for single-zone kind,Mongo-Sinkiang and Qinghai-Tibet especially Mongo-Sinkiang existed only.For cross-species,cross-Mongo-Sinkiang types accounted for 88.89% of the total species,followed by cross-Qinghai-Tibet,southwestern China,North China,while across central and southern China were limited.
