| 摘 要： | 从2002年11月到2003年3月，在四川宝兴蜂桶寨自然保护区设点，对该区域毛冠鹿冬季生境选择进行了研究．在单变量分析中，植被类型、坡位、郁闭度、竹子密度、老笋密度、乔木大小、草本覆盖率和空地面积8个变量在生境样方和对照样方间存在显著差异．Logistic回归的分析表明草本覆盖率、乔木大小和植被类型是影响毛冠鹿生境选择的主要变量．食性与气候是影响毛冠鹿冬季生境选择的两大主要生态因子．文中还就Logistic回归分析的结果与主成分分析的结果进行比较，两者结果基本一致．

| Abstract: | To understand the habitat requirements of the tufted deer,we have carried out a field research in Fengtongzhai Nature Reserve,Baoxing County,Sichuan Province from November 2002 to March 2003.In univariate analysis,8 variables(vegetation type,slope position,canopy,bamboo density,old shoot proportion,tree size,herb cover proportion and open land proportion) differed significantly between in habitat and control plots.However,only 3 variables entered the logistic regression equation,namely herb cover proportion,tree size and vegetation type,which indicated that they are the best indicators to discriminate habitat plots from control plots.Diet and climate are the two main factors influencing winter habitat selection of the tufted deer.The results from both logistic regression and principle component analysis were compared,and they are basically consistent. |
