摘　　要：目的　调查大理州洱源县小兽类哺乳动物种群结构。方法　 2 0 0 1～ 2 0 0 3年春季 ,在不同环境下采用捕鼠笼、鼠夹、电子捕鼠器等工具捕捉小兽 ,研究小兽种群结构。结果　捕获小兽 3目 5科 8属 17种共 661只。野外生境捕获小兽 3目 17种 ,以大绒鼠和齐氏姬鼠为常见种 ,分别占 3 2 .71%和 2 3 .5 9%。室内生境捕获小兽 2目 4种 ,褐家鼠为优势种 ,占 77.43 % ,黄胸鼠次之 ,占 18.75 %。结论　野外生境小兽种群丰富 ,室内较单一。Objective To study the population structure of small mammals in Eryuan Dali. Methods Small mammals were captured by mouse-trap in different habitats form 2001 to 2003 in spring. Results A total of 661 small mammals were captured and identified, which belonged to 17 species of 8 genera,5 families,3 orders. Seventeen species of small mammals were captured outdoor,of which E.miletus and A.chevrieri were the dominant species with constituent ratio 32.71% and 23.59% respectively. Four species were captured in house,of which the dominant species were R.norvegicus and R.fiavipectus with constituent ratio 77.43% and 18.75% respectively. Conclusion The population of small mammals was abundant in outdoor habitats while that in indoor habitats was simple.
