太白县湑水河流域大熊猫生境选择

Habitat Selection by Giant Pandas Distributed along Xushuihe River in Taibai Country

采用主成分分析与Vanderloeg(Wi)和Scavia(Ei)选择指数相结合的方法,研究了太白县湑水河流域黄柏塬保护区和牛尾河保护区大熊猫的生境选择。对13个项目进行了调查,结果表明:黄柏塬自然保护区主要影响因子是食物因子、干扰因子和植被因子,牛尾河自然保护区主要影响因子是食物因子、地理因子和植被因子;两个保护区的大熊猫在林型、乔木郁闭度、竹子长势、竹子平均高度、竹子密度、海拔、坡度、坡向、坡位选择上存在微差异,但在水源远近和有无伴生动物选择上是相似的。

Habitat selection by giant panda was studied by the combination of principal component analysis and Vanderloeg （Wi） and Scavia （Ei） index in Huangbaiyuan Nature Reserve and Niuweihe Nature Reserve along Xushuihe River in Taibai Country, Shaanxi, China. Thirteen items surveyed were measured. The results indicated that the main factors influencing the habitat selection by giant panda in Huang- baiyuan Nature Reserve were food, disturbance and vegetation, and in Niuweihe were food, landform and vegetation. There were insignificant differences for habitation selection of giant panda in forest type, forest canopy, growth condition of bamboo, average height of bamboo, density of bamboo, altitude, slope, aspect, slope position between two habitats. It was similar for giant panda to choose the distance of water and associated animals.
