摘要: 通过对内蒙古东部草原地区赤狐的25个洞穴观测, 运用系统聚类分析的方法, 研究了赤狐繁殖期的洞穴选择。结果表明, 影响赤狐繁殖期洞穴选择的主要因子是水源, 其次是坡向、坡位和坡度, 人为干扰、隐蔽程度及洞口朝向等因子对其影响作用不明显。繁殖期赤狐的最适洞穴选择为: 阳坡或半阴半阳坡、下坡位、坡度 5°~25°、距水源 500~1 000 m。

Abstract: The denning selection by red fox (Vulpes vulpes) during breeding period were studied in the northeastern Inner Mongolia during May 1995.By using the cluster analysis, the results shown that the ultimate factors which exerted notable influence on the denning selection by red fox was water source. The proximate factors were slope aspect, slope position and slope degree. Influence of human disturbance sheltering class, and direction of den entrance on dennin g selection by red fox during this period were exerted indistinctively. The optimal denning selection by red fox during breeding period were a)slope aspect: sunny or half sunny half shady; b) slope position: lower; c) slope degree: 5º-25º; d)distance from water source:500- 1000 m.
