摘要
目的探讨秦岭大熊猫产仔育幼洞穴的选择机制。方法对产仔育幼洞穴的性能和构造等物理参数及洞穴外部环境因子进行样方调查,通过系统聚类分析对所调查洞穴的物理属性进行分类。结果大熊猫产仔育幼洞穴选择的主要影响生态因子是坡型、干扰高度和隐蔽性等。结论洞穴内外生态因子的异质性是影响大熊猫洞穴选择的主要因素;大熊猫对偏岩型和隧道型两种洞穴具有较为相近的选择性。
Aim To Mountains. Methods research the selection of breeding dens by giant pandas during the breeding season in Qinling Study the capability, structures, and environmental factors of these dens, and analyze these factors by the systematic cluster analysis. Results The main factors influencing giant pandas＇selection of breeding dens include slope type, height of disturbance, sheltering class and so on, while the influence of dens type is not significant. Conclusion The study has revealed that the dominant factor of the dens selection is the heterogeneity of ecological factors inside and outside the dens, while the influence of the dens type is not significant.
