摘　　要：2015年9月至2016年的8月,对老河沟自然保护区内川金丝猴的栖息地选择进行了初步研究。根据猴群的活动痕迹,共设置了451个20 m×20 m的植物样方,测定了海拔、坡度、植被类型、郁闭度等11个生态因子。采用Vanderloeg-Scavia选择性指数和主成分分析的方法对这些变量进行了分析。结果表明:老河沟自然保护区川金丝猴偏好利用海拔1 800~2 800 m区域内的常绿落叶阔叶混交林、落叶阔叶林和针阔混交林。猴群选择半阳坡和半阴坡的下坡位活动;活动地点的坡度多介于0°~20°之间,很少利用﹥40°的陡坡。研究结果还表明,老河沟自然保护区的川金丝猴选择的活动区域对水源的距离也有特别的要求(0~50 m);另外它们选择郁闭度为50%~75%,乔木密度为20~30棵/400m2、灌丛盖度为25%~75%的林地活动。A preliminary study on habitat selection of Sichuan snub-nosed monkey(Rhinopithecus roxellana)was carried out from September2015to August2016in Laohegou Nature Reserve.Eleven ecological factors including altitude,slope degree,vegetation type,canopy cover and so on are measured in451plant plots(20m X20m),where active traces of Sichuan snub-nosed monkey are found.These variables are analyzed with the method of Yanderloeg-Scavia selectivity index and Principal component analysis(PCA).The results indicate that Sichuan snub-nosed monkey prefer to inhabit in the evergreen and deciduous broad-leaved mixed forest,deciduous broadleaf forests and mixed broadleaf-conifer forest,ranging from1800m to2800m,and to live in half sunny slope and cloudy slope of downhill,with a slope degree from0°to20°rather than over40°.The results also show that they favor the forest with25%~75%of shrub coverage,50%~75%of canopy cover and20~30per400m2oftreeden-sity,where the distance to water is less than50meters.
