The small-eyed field mouse belongs to the Murinae subfamily. It mainly lives in relatively humid forests and forest-steppes, and enters grasslands and desert steppes along river valleys and shrubs. In northern Xinjiang, it mostly lives in broad-leaved forests dominated by poplars and willows, coniferous forests dominated by spruce and fir, shrubs, and wheat, sesame and other crop fields in farmlands, as well as weedy canal ridges and submerged overflow zones. It is not found in desert areas. Previously, this species has always been considered to be the small wood mouse (<Apodemus sylvaticus>), but the results of biochemical and morphological studies, as well as molecular systematics and morphological studies, all believe that the small wood mouse is only distributed in western Europe. The small-eyed field mouse (<Apodemus uralensis>) distributed in Xinjiang and neighboring areas of my country was named in 1811, and the type specimen is located in the southern Ural Mountains of Russia.
