摘　　要：2006年12月、2007年7～8月对岷山北部4县的竹类开花及大熊猫活动情况进行了调查。结果表明：（1）该区域竹种单一，仅有华西箭竹Fargesia nitida和缺苞箭竹F．denudata两种竹类，其中华西箭竹的分布面积最大；（2）该区域竹类从2004年开始出现开花现象，到2007年调查时开花过程已基本结束，开花竹面积达73082hm^2，占竹类分布面积的51．36％；（3）在整个开花过程中，大熊猫实体被发现的频次增加，没有发现病、饿、死大熊猫的个体，现有大熊猫分布在竹类未开花的迭部县东部和舟曲县境内。此次竹类开花枯死，使该区域原有的大面积的大熊猫栖息地消失，因此需要加强对栖息地的保护和研究工作，使之尽快恢复成为大熊猫适合的栖息地。A survey on bamboo flowering and giant panda activity was conducted in north Minshan Mountains from December 2006, and July to August, 2007. The results showed that： 1 ） bamboo species in the survey sites consisted of only two species, Fargesia nitida and F. denudate, and the distribution of F. nitida was much wider. 2） Bamboo flowering in this area started in 2004 and mostly ended in 2007. The area of flowering bamboo was 73 082 hm^2 , representing 51.36% of the total bamboo in the area. 3） During the flowering, pandas were observed more frequently outside their regular habitat range and no sick, starving or dead pandas were found. At present the giant pandas probably exist in the east of Diebu and Zhouqu Counties. For such bamboo flowering events, many habitats in this area are no longer suitable for pandas, so it is necessary to strengthen the protection and research of habitats and potential habitats, restoring them to suitable habitats as soon as possible.
