摘　　要：2005年9月到11月初,作者在云南省维西县塔城乡格华箐对一群滇金丝猴的初秋生境选择情况进行初步调查.根据记录到的滇金丝猴活动位置设置50个20m×20m的样方,测定了12个生态因子(郁闭度、地形特征、海拔、坡向、坡度、植被类型、水源距离、人为干扰、乔木数量、死树情况、乔木胸径、地衣等级).对该群滇金丝猴初秋生境喜好程度分析表明,初秋时节,滇金丝猴喜欢在20°-40°之间的坡度、郁闭度在40%-80%之间的山坡坡面活动,活动区间一般在海拔2 700-3 300 m之间,对阔叶落叶林和针阔混交林比较喜欢,喜欢乔木的平均胸径>20 cm和远离人群(>500 m)的生境.尽管地衣是其主要食物,但对地衣和乔木数量的要求不高,对离水源的远近和活动地点有无死树无要求.对各种生态因子的主成分分析表明,前6个主成分的累积贡献率达到了78.37%,可以较好的反映初秋滇金丝猴的生境特征.Autumn habitat selection of the Yunnan snub-nosed monkey （Rhinopithecus bieti） was surveyed from September to early November 2005 at Gehuaqing region which geographically locates in 27°36′N, 99°18′E in Weixi county. Twelve ecological factors were measured from 50 plots where the monkey group ever stayed. These factors included canopy cover, geographical positions, elevation, aspects, slope degrees, vegetation types, the distances to rivers, human disturbances, the number of trees, deadwood, DBH （ diameters of breast height of trees）, lichens. The analysis indicated that R. bieti chose the slope face of mountain which is about 20°- 40°, altitude from 2 700m to 3 300m. And the canopy cover is between 40 - 80%. In early autumn, R. bieti preferred deciduous broadleaf or mixed deciduous broadleaf and conifer forests. The DBH is more than 20cm and human disturbance is more than 500m. The distance to water and deadwood contributed to little impact on the habitat use of R. bieti. Principal component analysis showed that the 6 former factors explained 78.37% of the total variance.
