摘　　要：对不同地区川金丝猴食物组成的比较有助于了解其对不同生境食物供应的适应性。本研究通过对陕西川金丝猴猴群食谱的长期记录,并汇集了国内对四川—甘肃和湖北的川金丝猴食性研究结果,集成了这三个地理种群川金丝猴各自的地域性食谱,共计有136种植物(隶属35科)被该物种作为采食对象。对来自这三个不同区域(陕西、四川—甘肃、湖北)的川金丝猴食谱组成的比较,发现有近半数的植物是三个地理种群共同的采食对象,但其食谱组成差异明显。这可能源于各地植物本身的多样性差异,及不同地理种群对各种食物采食偏好的不同所致。对其相关聚类分析结果显示,陕西和湖北的猴群在食谱组成上相近,但四川—甘肃的猴群与前两个地区猴群的食谱组成差异极大。然而湖北和四川—甘肃种群在食物的选择上采用了近乎相同的偏好倾向,而陕西的猴群与它们明显不同。我们初步分析认为造成食谱组成和采食偏好差异的原因可能是各地理种群活动地海拔带重叠度不同、森林类型不同、它们在不同林型中活动的时间分配不一。很明显,就我们目前所掌握的有关川金丝猴食谱组成来看,该物种不应该仅仅被认为是一个叶食性灵长类动物,而应该是一个泛化采食者。There have been no studies of food habits of golden snub-nosed monkeys （ Rhinopithecus roxellana） for over a decade,and descriptions of these diets are primarily qualitative. Comparing diets of golden snub-nosed monkey populations in different regions is important to understand foraging adaptation to different environments. We compared diets of three geographically distinct populations of golden snub-nosed monkey in Shaanxi,Sichuan,Gansu,and Hubei provinces. In total, 136 plant species belonging to 35 families were confirmed as foods of golden snub-nosed monkey. Although nearly half the plant families were shared among all populations,we found significant differences in the three diets. Dietary variation was influenced not only by plant diversity in those different habitats,but also by the feeding trees preferred by monkeys. Monkeys in Shaanxi and Hubei had a similar dietary spectrum,which differed from the populations in Sichuan-Gansu. However,monkeys in Hubei and Sichuan-Gansu showed a similar pattern on food preference whereas populations in Shaanxi exhibited a different food preference. Our analyses suggest that golden snub-nosed monkeys are generalist feeders rather than folivore.
