Abstract: The subgenus of rock voles，Alticola s．str．，is widely distributed over montane regions of Central Asia from the Himalayas and Hindu Kush through the Pamirs．TienShan and Tibet to Tuva．Khangai and Lake Baika1．Within its range，the subgenus displays a rather complicated pattern of morphological diversity，which makes it difficult to discriminate within-species variation from between-species differences．Apart from wellknown faunistic and taxonomic reviews in which the systematics of Altlcola was casually reviewed along with other taxa (e. g.et a1．，Ellerman，1941;Ellerman．1951;Gromova1．，1977；Corbet，l978；Honacki eta1．1982；Pavlinov et a1．1987) ,there have been few revisions based directly on a thorough analysis of original data (Hinton，1926；Heptner et a1．1968; Rossolimo et a1．1992a；Heilscher et al． 1992)．Due to differences in opinions of their authors on species concept，materials available, and technicaI methods employed，these works suggested drastically different classifications at species and subspecies levels．For instance，the number of species in Alticola S．str varied，according to the above revision,from one to 12．

摘要： 高山鼠平亚属(Alticola)广布于中亚山地，即从喜马拉雅山、兴都库什经帕米尔、天山、西藏而至图瓦、抗爱山和贝加尔湖一带。中国过去仅记录2种：银色高山鼠平(Alticola argentatus Severtsov；有时定作劳氏高山鼠平A.roylei的一亚种)和斯氏高山鼠平(A.stoliczkanus Blanford).本文主要依据形态学资料和采用判别函数分析的方法，对该亚属进行了研究。我们认为中国高山鼠平至少有3个以上的物种存在，现概述于后。
