摘要
目的调查青藏铁路沿线代表性地区鼠类种群构成,确定是否有褐家鼠分布。方法户外用鼠夹法,室内用鼠夹法、鼠笼法和粘鼠板法,分别在拉萨、那曲、林芝地区的居民区室内外、垃圾场、粮库、宾馆饭店等场所捕获鼠类,并进行形态学鉴定,计算鼠密度和鼠种构成。结果青藏铁路沿线的拉萨、那曲和林芝地区共布放1817个鼠夹(鼠笼、粘鼠板)/夜,捕鼠126只,未捕获褐家鼠。拉萨和林芝地区以黄胸鼠为优势鼠种,分别占84.1%和70.0%,那曲县以小家鼠为主,占98.1%。结论3个地区的居民区以黄胸鼠和小家鼠为优势鼠种,未发现褐家鼠分布。
Objective The species of rodents was investigated along the Qinghai-Tibet Railway in representative areas where Norway rats （Rattus norvegicus） might be distributed in Tibetan Autonomous Region. Methods Rodents were trapped by snap trap, live trap and glue boards in different habitats in Lhasa, Nagqu and Nyingchi. The rodents captured were identified, then the densities and population constitutes of them were calculated. Results A total of 126 rodents were captured with 1817 snap traps. R.norvegicus did not be eaptured in the areas investigated. R.tanezumi was the dominant specie in Lhasa and Nyingchi, accounting for 84.1% and 70.0% respectively, while Mus musculus in Nagqu accounted for 98.1%. Conclusion The dominant species of rodents are R.tanezumi and M.musculus in the residential areas investigated, and no R.norvegicus was found.
