Abstract: There are 87 species(including 7 subspecies) of glires in Gansu province,belonging to 2 orders. 9 families and 41 genera. The fauna of glires consists of three camponents : The palaearctic species,the oriental species and the widely spread species.
Based on the faunistical characteristics of glires and zoogeographical feature,Gan su may be divided into 6 zoogeographical provinces.

P.prezewalskii are characteristical species.
4. The province of Qilian Mountainous Region There are 29 species of glires,making up 33.33% of total among them 24 belo g to palaearetic。1 belongs to oriental and 4 belong to widely spread species.Alticola stoticzkanus nanschanicus & Alticola argentatus leucurus are characteristical ones.
5 .The province of South -Gansu Plateau Grasslands:There are 34 species of gllires,making up 39.08% of total,among them 23 belong to palaearctic,6 belong to oriental and 5 belong to widely spread species. Microtus arvalis obscurus & Clethrionomys rufocanus shanseius are of characteristics.
6 .The province of South-Gansu Mountainous Region There are 34 species of glires,making up 39.08% of total; among them 10 belong to palaearetie, 12 belong to oriental and 12 belong to widely spread species. Hystrix hodgsoni subristata and Micromys minutus are characterristical species.
