摘    要:通过对内蒙古东部草原64个沙狐洞穴的观测,采用主成分分析法,对沙狐洞穴选择作了初步的定量研究。分析结果表明:影响沙狐春季洞穴选择的主要生态因子有7种,依次为:坡位因子(随坡度,坡高的变化而变化),水源因子,植被因子,微气候因子,食物因子,人为干扰因子和微生境因子,而坡向,洞口朝向及洞道口倾角等影响不明显。

关 键 词:内蒙古东部草原  沙狐  春季  洞穴选择

Abstract:This study investigated the selection of dens of the corsac fox during May 2001 in the prairie of eastern Inner Mongolia We observed 64 dens found and used principal component analysis to analyze the results Seven factors affecting the selections of dens of corsac fox in decreasing order of importance were as follows: slope position(varying with slope degree and slope height),water source, vegetation, microclimate, food, human disturbance,and microhabitat However, the influence of food abundance, slope direction, and direction as well as inclination of the den entrance on the den selection of corsac fox was insignificant
Keywords:Corsac fox( Vulpes corsac )  Den selection  Principal component analysis
