峨眉山啮齿类和食虫类秋季相对密度调查

2002年9月28日～l0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20种中，相对密度较大的为高山姬鼠(Apodemus chevrieri)占26．09％、龙姬鼠(Apdemus draco)占18．26％、长尾姬鼠(Apodemus sylvaticus)占15．65％及四川短尾鼩(Anourosorex squamipes)占l0．43％；在5个典型生境样点中，金顶(15．33％)、雷洞坪(20．99％)和仙峰寺(13．95％)3处的兽类相对密度较大，但清音阁(1．01％)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，有待进一步研究。

INVESTIGATION ON RELATIVE DENSITY OF RODENTIA AND INSECTIVORA IN MT EMEI IN AUTUMN

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.
