摘要：

2008年4月至2010年7月，在呼玛县三卡乡老道店村为中心（51°16′08.3″N，126°42′14.4″E，海拔201m）的半径为10km的范围内采用系统抽样法（system sampling）和多元统计分析方法(multivariable statistic analysis)对胎生蜥（Lacerta vivipara）的生境选择进行了研究。结果表明：胎生蜥对植被类型、食物丰富度、坡向、落叶层厚度、天敌干扰、坡度、植被盖度、人为干扰、土壤质地及坡位等10项生境因子具有选择性。在大兴安岭东麓胎生蜥繁殖期的最适生活环境是土质疏松、林间落叶层较厚、处于中、下坡位且面积较大并坡度平缓的蒙古栎——黑桦混交林。

Abstract:

By using system sampling and multivariable statistic analysis method, we research on the habitat selection of Lacerta vivipara in the range 10 km at Huma country, Heilongjiang province during the stage of April-May, 2008 and May-June, 2009 and July, 2010. The result shows that L. vivipara showed selection behaviors on habitat. The vegetation type, slope aspect, natural enemy disturbance, slope gradient, food abundance, vegetation canopy, human disturbance, soil texture, slope location and forest floor thickness effected L. vivipara significantly. L. vivipara were apt to select habitat with less human disturbance and spacious Quercus mongolica-Btula davurica mixforest. They lived in middle and lower slope with thicker community forest floor and loose soil.
