摘　　要：2001年对大相岭大熊猫及栖息地进行了调查，调查结果表明：大相岭山系有大熊猫栖息地面积353.76km^2，数量14只，分布在洪雅和荥经县境内，大熊猫活动痕迹主要分布在海拔2000-2500m的针阔混交林生境．大熊猫栖息地内存在多种人类活动干扰，主要有采笋、历史的采伐和公路，分别占调查样方数的23.2％、22.2％和6．8％．与20世纪80年代进行的第二次调查比较，大熊猫的分布范围发生了较大的改变，当时没有大熊猫分布的荥经县现成为大熊猫的主要分布地．大相岭山系是现存大熊猫栖息地面积最小，数量最少的山系，需加强该地的保护区建设、大熊猫生境廊道建设及有效控制栖息地内的人类干扰活动，从而避免大熊猫种群的衰亡，The results of the 3^rd Nationalwide Giant Panda Census in 2001 show that the total area of the giant pandahabitats is 353.76km^2, population size of the giant panda is 14 individuals in Hongya and Yingjing County of the Daxiangling Mountains. Of all of the giant panda traces, 82 % were observed between the elevation of 2000-2500m in the conifer-broadleaf mixed forests. In 23.2%, 22.2% and 6.8% of sampling plots bambooshoots collecting, logging and highway building occurred, which suggests that human activities disturbed the habitats of giant pandas. Distribution of the giant panda in the Daxiangling Mountains has changed since the 2^rd Nationalwide Giant Panda Census in 1980＇s. Quite a few individuals of the giant panda were surveyed in Yingjing County, but no individual occurred here in the 2^rd Nationalwide Giant Panda Census. Because of their population sizeand area of habitats are the least among all mountains, conservation of the panda population and their habitatsin the Daxiangling Mountains must be of superiority. Effective measures should be taken to enable conservation, such as to establish corridors and reduce human activities in giant panda habitats.
