摘　　要：20 0 2年 9月 2 8日～ 10月 6日 ,主要用铗日法对四川峨眉山啮齿类和食虫类进行调查 ,得出以下结论 :被捕的 2 0种中 ,相对密度较大的为高山姬鼠 (Apodemuschevrieri)占 2 6 .0 9%、龙姬鼠 (Apodemusdraco)占 18.2 6 %、长尾姬鼠 (Apodemussylvaticus)占 15 .6 5 %及四川短尾 (Anourosorexsquamipes)占 10 .4 3% ;在 5个典型生境样点中 ,金顶 (15 .33% )、雷洞坪 (2 0 .99% )和仙峰寺 (13.95 % ) 3处的兽类相对密度较大 ,但清音阁 (1.0 1% )和报国寺 (0 )二处的相对密度很小 ,导致其显著差异的具体原因尚不清楚 。During September 28 to October 6, 2002, an investigaion on Rodentia and Insecti vora in Mt Emei has been carried out mainly by traps, and the results are as fol lows: Among the 20 species caught, the species with higher relative densities in cluded Apodemus chevrieri (26.09%), Apodemus draco (18.26%), Apodemus sylvaticus (15.65%) and Anourosorex squamipes (10.43%). In the tipical sit es, the relative densities are higher in Jinding (15.33%), Leidongping (20.99%) and Xianfengsi (13.95%) but it was much lower in Qingyinge (1.01%) and Baoguosi (0). However, the reason leading to such distinct results is still unknown and need to be researched further.
