摘要
2011年9月到11月,对四川省白河自然保护区的下平地川金丝猴进行野外跟踪研究,根据金丝猴活动的位置,设置了95个20m×20m的样方.在样方中,就11个生态因子(海拔梯度、距水源距离、地形、坡向、坡度、林型、乔木高度、乔木平均胸径、乔木密度、郁闭度、干扰强度)进行调查分析,来了解白河自然保护区下平地川金丝猴秋季生境的选择性.结果表明:白河自然保护区下平地川金丝猴群完全选择原始森林,倾向于乔木平均高度>15m和乔木平均胸径在16-30cm之间的落叶阔叶林和针阔混交林中活动,回避完全的针叶林,远离人为干扰.对郁闭度的要求一般倾向于25%-75%之间.活动海拔主要集中在2 300-2 900m之间.猴群趋向于山的中下部的坡度在20°-40°之间的西北﹑北﹑东北﹑东坡的地域活动.猴群对水源因子的选择无特别的偏好.对各个生态因子进行主成分分析,结果表明其中有5个主成分的特征值大于1,累积贡献率为72.1%,研究表明白河自然保护区川金丝猴秋季生境的选择受食物因子、环境质量、地理条件的共同影响.
From September to November in 2011, to explore the preferred habitat features for golden monkeys in auntumn, a wild reasearch was undertaken in BaiHe Nature Reserve. In this paper, a series of habitat factors （including elevation gradient, distance to water, terrain, slope, gradient, type of forests, height of trees, average diameter of the trees, density of trees, density of canopy, interference） in the golden monkey＇s high-frequency activity areas of Xiapingdi in the Baihe Nature Reserve were investigated, and the relations of these factors with the locations of golden monkeys in Autumn were analysed. The results indicated that the deciduous broadleaf mixed forest and coniferous and broadleaf mixed Forest were optimal living vegetation community for Baihe golden Monkey in autumn. The preferable height of trees was more than 15 m; the suitable diameter breast height was 16 -30 cm, the canopy density was 25 % - 75 % , the optimal living altitude was 2300 - 2900 m, and the slope was 20 - 40 degress among the northwest, north, northeast and east of mountain. Principal component analysis of 11 ecological factors showed that the edible food available, environmental quality, geographic conditions, but not water, were the main limiting factors for habitat selection of Baihe golden Monkey in autumn in Baihe Nature Reserve in Sichuan.
