摘　　要：采集了甘肃省白水江自然保护区2007～2009年监测数据的149个大熊猫活动痕迹点,利用SPSS软件对坡向、坡度、竹种盖度、竹子生长类型、竹子生长状况、海拔和水源7个生境特征变量进行主成分分析,结果显示诸变量的重要性由高到低依次为坡度、坡向、竹子生长状况、海拔、竹种盖度、竹子生长类型和水源,X^2适合度检验各生境变量内部不同组分之间均存在极显著差异(P<0.01),表明影响该区大熊猫活动的主要环境因素首先是以坡向和坡度为代表的地形因素,其次为以竹子生长状况、海拔、竹种盖度、竹子生长类型为代表的食物和隐蔽因素,水源对大熊猫活动的影响不显著。149 active trace points of the giant panda were collected from monitoring data in Baishuijiang National Nature Reserve, Gansu province, during 2007 to 2009. Seven habitat characteristic variables （ aspect, gradient, the cover degree of bamboo species, type of bamboo growth, the condition of bamboo growth, altitude, and water source） ,were analyzed by the principal component analysis using SPSS software. The results showed that the importance of various variables from high to low were gradient, aspect, the condition of bamboo growth, altitude, the cover degree of bamboo species, type of bamboo growth, and water source. Through the X2 fitness test, we found there are extremely significant differences （P 〈 0. 01 ） among the different components within the habitat variables. The results indicated that the main environmental factor, which has influence on the activities of the giant panda in the area, firstly was the topographic factor represented by aspect and gradient, second was the food and hidden factor represented by the condition of bamboo growth, altitude, the cover degree of bamboo species, and type of bamboo growth. The water source had no significant impact on the activity of the giant panda.
