摘要： 采用野外调查方法，对小河沟自然保护区内大熊猫利用生境和人工林环境的差异性进行研究。结果显示：两种环境在郁闭度、灌木盖度、竹子盖度、乔木密度、灌木密度、竹子密度6个方面存在显著差异（P < 0.05），其中，以乔木密度、灌木密度和竹子密度作为判别因子构建的判别方程，对两类环境的正确判别率为98.15%。与大熊猫利用的生境相比较，人工林的环境特征是：乔木密度比较大，但灌木密度和竹子密度比较小。人工林环境难以满足大熊猫对生境的需求，结果能够为大熊猫生境的恢复工作提供重要参考。Based on the field survey in Xiaohegou Nature Reserve, the difference between the habitat used by giant panda and man-made forest was studied. The results showed that 6 variables differed significantly between the habitat used by giant panda and man-made forest, they were canopy, shrub coverage, bamboo coverage, tree density, shrub density and bamboo density, respectively (P < 0.05). The discriminant equation composed of tree density, shrub density and bamboo density had a correct prediction rate of 98.15%. Compared with the giant panda habitat, the man-made forest was characterized by higher bamboo density, but lower in shrub and bamboo density. The man-made forest was not easy to fulfill the habitat requirements of giant panda. These results could provide important references for the restoration of the giant panda habitat.
