摘要： 主要对云南省剑川石龙地区的小型哺乳动物的群落组成和多样性进行了研究，石龙地区共分布小型哺乳动物23种，分属4目、7科。调查于2002年—2014年的13年间共布鼠笼171 482个，共捕小型哺乳动物15 338只，捕鼠率为8.94%。其中高山姬鼠7009只，大绒鼠6471只，两者占捕获动物的87.89%，其余21种动物仅占12.11%。大绒鼠和高山姬鼠数量的年间变化差异不显著，但是月份间差异极显著，其中两种鼠类的捕获率较高的月份集中在夏季。4种生境小型哺乳动物的数量差异极显著，其中在室内住家附近区域最少，而在灌丛中分布数量最多。以上结果表明石龙地区的小型哺乳动物多样性较丰富，啮齿动物的数量是和其繁殖季节密切相关。

Abstract: Community composition and diversity of small mammals from Jianchuan Shilong region in Yunnan Province were studied in the present study. The results showed the total distribution of small mammals in Shilong area including 23 species, belonging to 4 orders, 7 families. A total of 13 years of cloth cage 17 1482, a total of 15 338 small mammals were captured, with the capture rate of 8.94%. Of which Apodemus chevrieri was 7009, Eothenomys miletus was 6471, which accounted for 87.89% of the total mammals, remaining 21 captured animal species accounted for only 12.11%. Changes of number in E. miletus and A. chevrieri showed no significant difference among different years, but had significant differences among months, the capture rates of the two rodents were higher in the concentrated in summer. The number of small mammals showed significant differences in four small mammal habitats, which were lower in indoor neighborhood region, and higher in the shrub. These results indicated of that small mammals in Shilong area were rich in diversity, and the number of rodents was closely related to the breeding season.
