云南老君山鼠类的垂直分布

1980年6月至8月,我们对云南老君山的鼠类进行了垂直分布的调查研究。现介绍如下。 自然概况 老君山位于云南省的剑川、丽江和兰坪三县交界处;北纬26°30′—26°52′,东经99°42′—100°26′。属于著名的横断山脉的云岭山系中的大山之一。最高峰海拔4,247m.,山麓(金坪)海拔2,500m.。山势南北走向,北高南低,有纵横交错的高山、山间峡

THE VERTICAL DISTRIBUTION OF RODENTS OF LAOJUN MOUNTAIN, YUNNAN

A survey of the vertical distribution of Rodents was made in June to August, 1980 at Laojun Mountain, Yunnan. The topography was divided into four vertical zones, 2, 500-3, 000m., 3, 000-3, 500m., 3, 500-4, 000m., and 4,000-4, 247m., respectively. The results are shown as tab. 1 -2. and tig. 1 -2. 1. Altogether set 9,358 mouse traps in four vertical zones. 1,054 Rodents were obtained. Captured 11 species of mouse (Eothenomys custos rubellus, Eothenomys miletus miletus, Apodemus chevrieri, Apodemus draco orests, Apodemus latronum, Rattus norvegicus socer, Rattus coxing andersoni, Rattus flavipectus, Rattus niviventer confucianus, Rattus nitidus nitidus, and Mus musculus). Total capture rate is 11.26% percent. 2. The component species the number index of each species of Rodents in Laojun Mountain were varied according to the vertical zonal variation with respect to the differences of altitudes, flora and natural environmental conditions.
