1. There are 14 species of bamboos belonging 6 genera in the distribution area of
Giant panda in the Qinling,but only 3 species belonging 3 genera to form the food base of Giant panda: (1)Bashania fargesli. (2)Thamnocalmus spathacea， (3)Sinaru-ndinaria nitida. 2.The bamboo resource can meet the needs of at least 7 times the numbers of Giant panda at present.
3. According to different topography，bamboo forest and Giant panda active peri-
ods etc，the types of food base can be classified into three categories：(1) Mixed bamboo area at below midhill with steep slope and canyon, (2) Com pound-axis demut-ation bamboo area at middle mountain with gently slope and wide valley，(3)Symp-ode scattered bamboo area at subalpine with broad ridge and peak.
