摘　　要：甘泉县有啮齿动物１４种，隶属２目，５科，１０属．其中鼠科、仑鼠科、松鼠科共有１２种，占总种数的８５．７％；广布种占２１．７％，东洋界种占７．２％，古北界种占７１．４％．在古北界种中，华北区的占８０％，蒙新区的占２０％．通过纬向、经向地带性分析，认为甘泉县鼠类区系在纬向上具有华北区黄土高原亚区北部边缘地带的特征，在经向上与晋西高原的鼠类区系更为接近，与陇东高原则相对较远，甘肃鼢鼠是陕北林区最主要的林地害鼠。species of rodent in Ganquan County belong to 2 orders, 5 families and 10 genus, in which 12 species belong to Muridae, Cricetidae and Sciuridae that is 85.7%of total species. The wide distributed species is 21.7%, oriental kingdom species is 7.2%, ancient Norther kingdom species is 71.4%. In the ancient Norther kingdom species, 80% belongs to Norther of central China region and 20% belongs to Mengxin region. Through the latitude and longtitude zonal analysis, it is showed that the muroid fauna in Ganquan Counth holds a feature of northern edge zone in loess plateau lomgtitudely and similar with muroid fauna in Jinxi plateau latitudely, it is far away from the Longdong plateau fauna. The Gansu sokhor is a major muriod damage in the forested land of Norther Shaanxi.
