Species and fauna distribution of rodents in Northeast China

目的调查研究东北地区啮齿动物种类和区系分布。方法采用现场捕获啮齿动物鉴定和文献分析相结合的方法。结果东北三省的啮齿动物现知7科26属43种,111县市有分布,其中黑龙江省6科21属28种,35县市有分布;吉林省7科23属32种,36县市有分布;辽宁省5科22属32种,40县市有分布。区系分布研究结果表明,东北区分布37种,其中大兴安岭亚区分布20种,长白山亚区分布25种,松辽平原亚区分布28种;蒙新区东部草原亚区分布31种。4个亚区均有分布的广布种13种:花鼠、黑线仓鼠、大仓鼠、东北鼢鼠、棕背鼠平、麝鼠、莫氏田鼠、长爪沙鼠、巢鼠、朝鲜姬鼠、黑线姬鼠、褐家鼠、小家鼠。结论种类和区系分布调查为东北地区啮齿动物的区系分布和防治研究提供了科学依据。

Objective To study species and fauna distribution of rodents in Northeast China. Methods The combination of rodents captured were identified on field and literature analysis was carried out for species and fauna distribution of rodents in Northeast China. Results There were 43 species 26 genera and 7 families rodents known in Northeast China,of which 28 species 21 genera and 6 familes were distributed in 35 counties and cities of Heilongjiang Province,32 species,23 genera and 7 families in 36 counties and cities of Jilin Province,and 32 species,22 genera and 5 families in 40 counties and cities of Liaoning Province. Investigations of fauna distribution showed that 37 species were distributed in Northeastern district,of which 20 species were distributed in Daxinganling subterritoy,25 species in Changbaishan subterrtoy,and 28 species in Songliao-plains subterrtoy and 31 species in Eastern-grasslands subterrtoy of Mongolia-xingjiang district. The rodents species of extensive distribution in 3 subterrtoy were Eutamias sibiricus,Cricetulus barabensi,Tscherskia triton,Myospalax psilurus,Clethrionomys rufocanus,Ondatra zibethica,Microtus maximowiczi,Meriones unguiculatus,Micromys minutus,Apodemus peninsulae,Apodemus agrarius,Rattus noruegicus,Mus musculus. Conclusion The investigation provides the base for study on fauna distribution,monitor of vecotor population,and control of rodents in Northeast China.
