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 investigate the rodent species and floristic distribution in Northeast China. Methods The method of combining field identification with rodent identification and literature analysis was used. Results The rodents in the three northeastern provinces now know 43 families, 26 genera and 7 families, with distribution in 111 counties and cities. There are 28 species and 21 genera in Heilongjiang Province, with distribution in 35 counties and cities. There are 32 species and 23 genera in 7 families in Jilin Province and 36 counties and cities Distribution; Liaoning Province, 22 genera and 32 species, 40 counties have distribution. The results of floristic distribution indicate that there are 37 species distributed in northeastern China, among which there are 20 species distributed in Daxing’anling sub-region, 25 species distributed in Changbai Mountain sub-region, 28 species sub-region in Songliao plain and 31 species sub-region in the eastern part of Mengxin region. There are 13 widely distributed species in 4 subregions: rat, black hamster, hamster, northeastern zoo, brownback, muskrat, moth vole, gerbil, gerbil, , Apodemus agrarius, Rattus norvegicus, Mus musculus. Conclusion The investigation of species and floristic distribution provides a scientific basis for the study of rodent flora distribution and control in northeastern China.
