Abstract: The key factors for nest site selection of Blyth's vole (Phaiomys leucurus) were analyzed in the Altun Mountain National Nature Reserve, Ruoqiang County, Xinjiang. A total of 261 sample areas, each consisting of 5 m × 5 m quadrants, were selected between 2011 and 2013.  Of these, 40 sample areas contained a vole nesting site. The degree of canopy cover, the number of plant species, vegetation cover, vegetation height, vegetation density, soil hardness, and distance to the nearest road were determined for each area. The Vanderloeg and Scavia Election Index, and Principle Component Analyses (PCA) were used to identify the principle components in habitat selection by Blyth’s vole. The results showed that there were highly significant differences in vegetation height and density, in the numbers of the plant species, and in soil hardness (P ?0.01) when comparing the nest sites and the random sites. According to Principal Component Analysis (PCA), the main factors affecting the nest site choice by Blyth’s vole were canopy cover, vegetation height, the number of differing plant species, and soil hardness. The Vanderloeg and Scavia Election Index indicated that Blyth’s vole prefers to burrow into areas with softer soil (3-4 kg/m2), areas whose vegetative microhabitat stands at a height of less than 8 cm, and areas with a section of low-lying canopy which provides hiding cover whose height is also less than 8 cm. Blyth’s vole preferred locations with fewer plant species, with canopy cover and vegetation low in height, and with softer soil.

摘要: 2011-2013年夏季,在阿尔金山国家级自然保护区高山草甸和高山荒漠区,累计调查样方261个,其中白尾松田鼠穴居地洞群利用样方40个。利用主成分分析法、Vanderloeg 和 Scavia 选择指数分析白尾松田鼠穴居栖息地选择的影响因子。结果表明,穴居地和对照样方在植物种类、植被高度、植被盖度和土壤硬度等方面差异极显著(P<0.01)。主成分分析表明,影响白尾松田鼠穴居地利用的主要因子为隐蔽级、植物高度、植物种类和土壤硬度。白尾松田鼠喜欢选择少于4种植物、高度小于8cm、土质较软(3-4 kg/cm2)、隐蔽级在 8cm 以下的栖息地。白尾松田鼠更偏爱植物种类较少,植被高度更低,而隐蔽级更低,土壤更软的栖息地。
