摘要: 目的:研究云南省大理市小兽类种群结构。方法:2000年10月至2002月5月,在不同生境采用捕鼠笼、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6科13属23种,共1132只。室外生境捕获小兽3目23种,以齐氏姬鼠和大绒鼠为常见种,分别占27.38%和16.15%。室内生境捕获小兽2目3种,褐家鼠为优势种,占72.20%,黄胸鼠次之,为27.41%。结论:室内、室外生境小兽的种群结构有很大差别。

Abstract: Objective:To study the population structure of the small mammals in Dali,Yunnan.Methods:Small mammals were captured by mouse-trap in different habitats from October 2000 to May 2002.Results:1132 small mammals were captured.They were identified as 23 species,belonging to 13 genera,6 families,3 orders.Twenty-three species of small mammals were captured outdoor,A.chevrieri and E.miletus were the dominant species,its constuent ratio were 27.38% and 16.15% respectively.Three species were captured inside house,the dominant species were R.norvegicus and R.flavipectus,its constuent ratio were 72.20% and 27.41% respectively.Conclusion:The population structure of small mammals was much different from indoor to outdoor habitats.
