摘要: 河西走廊位于甘肃省的西北部,为历史上通往我国新疆及中亚大陆的交通要道,以丝绸之路而闻名于世界。19世纪末,一些外国学者及旅行家曾对河西走廊作过动物学方面的调查。解放后,中国科学院甘青调查队于1958—1960年对河西地区的兽类进行了调查。随着自然疫源地普查工作的深入开展,省、地、县的有关卫生防疫专业机构,对河西走廊的部分地区和县(市)做过一些动物学方面的工作,但专门对啮齿动物地理分布进行较大范围的调查还不多。我们于1982年4—8月对河西走廊的马鬃山、安西、敦煌、金塔等地进行了调查,现报道如下。

Abstract: The Hexi Corridor is situated in northwest Gansu, it is a part of the west desert subregion in the Mongolia-Xinjiang area. It is of desert and semi-desert ecotype. There are altogether 4 families and 21 species of rodents in the Hexi Corridor.The rodents of desert and semidesert fauna in the Hexi Corridor are mainly composed of 5 species of Gerbillinae and 8 species of Dipodidae, and these species account for 60% of the rodents in the Hexi Corridor.The habitats of rodents in the Hexi Corridor can be divided into six types as follows:1. Sandy desert type: the main habitat of Meriones meridianus.2. Gravel desert type: the main habitat of Dipus sagitta.3. Piedmont plain desert type: the main habitat of Allactaga sibirica,4. Oasis type: the main habitat of Dipus sagitta and species of Cricetinae and Muridae.5. Wasteland type: the main habitat of Dipus sagitta and Allactaga sibirica.6. Salt-soaked desert and depression type: the main habitat of species of Dipodidae.
