摘要
通过绝对数量调查表明，在位于小凉山山系的马边大风顶大熊猫野外观察站约２０ｋｍ２（平面面积）的研究区域里，共有９只大熊猫，其中幼少组４只，青壮组２只，中年组２只和老年组１只．其年龄结构金字塔属于锥形，显示出略有增长趋势．环境中主要供食于该大熊猫社群的竹子有大叶筇竹和箬竹，而分别位于海拔较高的冷箭竹和海拔较低的刺竹成为大熊猫的食物资源．
Statistics of the exact number of giant pandas suggests that there are nine giant pandas in the study area(about 20 km 2)in the Dafengding observation station in the Liang Mountain Ranges.The population consists of 4 cubs and juvenniles,2 adults,2 middle aged and 1 old aged.The age pyramid indicates that the population is increasing slightly.There are four species of bamboo eaten by the giant panda in the area.The Qiongzhuea macropylla and Indocalamus longiauritus are the main food resources while the Chimonobambusa pachystachys and Bashania fangiana are reserved food resources.
