田鼠亚科（Arvicolinae） Microtini族（Tribe）全世界有10属81种。在中国有7属24种，分别是Arvicola （1种）, Lasiopodomys（3种）, Microtus（12种）, Neodon（4种）, Phaiomys（1种）, Proedromys （1种）和 Volemys（2种）。加上近年来中国发表的2个新种，总计是26种。Microtini族欧洲和北美分布种属的研究已经很清楚，但中国分布的在属级和种级分类阶元的分类都很混乱，长期存在争议。主要原因是它们集中分布在横断山系，除命名系列标本外（大多是100年前后国外科学家命名），没有可供研究的标本。本研究拟采集中国有分布的所有种的标本，通过经典分类学、阴茎形态学和分子系统学研究，解决中国有分布的Micortini族种属的分类地位和系统发育关系。

Microtini tribe of Subfamily Arvicolinae include 10 genera and 81 species in the world. In China,Microtini tribe include 7 genera 24 species. They are Arvicola （1 species）, Lasiopodomys（3 species）, Microtus（12 species）, Neodon（4 species）, Phaiomys（1 species）, Proedromys （1 species）,and Volemys（2 species）。In recent years, Chinese scientists published two new species: Proedromys liangshanensis and Neodon linzhiensis.So this tribe has 26 species in China. Microtini genera and species which distribut in Europe, Northern America and Central America were profoundly studied in morphological, taxonomic, ecological and phylogenetic systematics aspects.But Chinese genera and species of Microtini were put very few studies. So the status of genera and species have been disputing up to now.And systematics of this tribe are also not confirmed.The main difficulties are no specimens and tissues for studying after the nominating list. This study, we will collect all topotypes of Chinese species of Microtini tribe.And detect their morphology,taxonomy,glans penes morphology, and molecular phylogenetics for clarifying the controversies.
