| 摘 要： | 2008和2009年3—5月，采用直接观察法对广西宜州龙江河畔赤腹松鼠春季栖息地的选择进行调查和分析，结果表明：赤腹松鼠喜欢郁闭度好、水源距离10-50m、坡度20—40°、避风性良好、坡向东坡和南坡、坡位中坡位或上坡住、食物因子良好，人为干扰距离10-20m，海拔50—150m，乔木密度〈50株，灌木密度50～200株，乔木距离1～4m，灌木距离〈2m的栖息地；水源距离、坡度、海拔、灌木距离、人为干扰距离和灌木密度无显著差异（P〉0．05），郁闭度、避风性、坡向、坡位、食物因子、乔木密度和乔木距离存在显著差异（P〈0．05）。

| Abstract: | Habitat selection of the Callosciurus erythralus was investigated in Long Yangtze Riverside Guangxi from Mar to May 2008 and 2009. The result showed that canopy density well; Water distance10 -50m; Slope20 -40°; Shelter of wind good; Aspect eastern and southern; Slope position uphill and middle; Distance to human disturbance10 - 20m; Elevation50- 150m; Tree density 〈 50; Shrub density 50 -200; Distance of treel -4 m; Distance of Shrub 〈2 m; Food abundant Richness, Fitness tests showed that： Water distance; Slope; Elevation ; Shrub distance; distance to human disturbance and shrub density has no significant difference （P 〉 0. 05 ）, Canopy density, Shelter of wind; Aspect, Slope position, Food abundant, Tree density and Tree distances have significantly different （ P 〈 0. 05）. |
