秦岭南坡野生大熊猫繁殖交配期的生境选择

2002～2004年在秦岭南坡的佛坪和长青国家级自然保护区内对大熊猫在繁殖交配期的生境状况进行了取样调查,对样方生境的13个主要环境因子进行了测量.经初步因子分类和主成分分析.结果表明,在秦岭南坡大熊猫繁殖期的生境选择中,最重要的影响因子是食物因子,其次是植被因子.地理特征因子、隐蔽条件因子、干扰因子等因地区自然背景的差异而产生不同的影响.在两个不同的保护区内,繁殖期的大熊猫对生境的选择具有一定的差异.

A Study on Habitat Selection of Giant Panda in Reproduction Period in South-slope of Qinling Mountains

The habitat selection of giant panda in reproduction period in Foping nature reserve and Changqing nature reserve was studied in 2002~2004. 36 vegetation sampling plots and 180 bamboo sampling plots were set up for factor analysis and principal component analysis. Results indicated that food factor and vegetation factor are the most important ones affecting habitat selection of giant panda in its reproduction period. Landform factor, concealment factor, and disturbance factor have different affection based on different circumstances. The habitat selection of giant panda in reproduction period is different between two reserves.
