Abstract: The giant panda's selection for bamboo resources was studied in Mabian Dafengding Reserve from 1991 to 1993 in Liangshan Mountains. Vanderploeg and Scavia selectivity index was used to assess the panda's selection for different bamboo parameters. The selectivity index indicated that pandas had obvious selection for the different kinds of bamboo species. Pandas ferpered to feed on Qiongzhuea macrophylla and yushania glauca, almost avioded Chimonobambusa pachstachys. While feeding on Qiongzhuea macropgylla, they perfered to choose thick shoots(basal diameter>18mm) and young stems. While feeding on yushania glauca, they also perfered to select thick stems(basal diameter>12mm), and thick shoots( basal diameter>16mm), but no obvious selection for the old and the young stems.
