摘　　要：目的了解不同海拔地区小型兽类的种类及分布,为研究人兽共患病提供科学依据。方法在不同海拔区采用夹夜法调查小型兽类数量及分布。结果布放鼠夹2 120个次,捕获小兽155只,密度7.31%,其中高海拔区捕获动物12种,捕获率8.24%,以锡金小鼠为优势种;中海拔区捕获动物10种,捕获率7.79%,以斯氏家鼠为优势种;低海拔区捕获动物12种,捕获率6.05%,以黄胸鼠为优势种。结论不同地区小兽的种类、数量及分布不同,小兽密度随海拔升高而增高,黄胸鼠密度随海拔升高而降低。Objective To understand small mammals population structure and distribution in different altitude regions,and provide a scientific basis for studying zoonosis.Method Adopting night trapping method to survey the number and distribution of small mammals in different altitude regions.Results We had placed traps 2 120 times and captured 155 small mammals,the density was 7.31%.12 species animals in high altitude with the capture rate of 8.24%,the dominant species was Xijin mice.In intermediate altitude regions,10 species were captured with the capture rate of 7.79%,the dominant species was Rattus rattus sladerni.12 species in low altitude and the capture rate was 6.05%,Rattus flavipectus was the dominant species.Conclusions The species,numbers and distribution in different altitude regions were different,with the level of altitude increased,the density of small mammals increased too.However,with the level of altitude increase,Rattus flavipectus density decreased.
