Abstract: Although belonging to the order Carnivora,the giant panda has specialized on a bamboo diet. Bashania spanostachya Yi and Yushania lineolata Yi are the major food sources for giant pandas in Liziping Nature Reserve,Sichuan Province, China,imposing great influences upon their long-term survival and reproduction. In order to uncover their diet composition in summer and the effect of stem age and part on the biomass of B. spanostachya and Y. lineolata,we established 60 plots along elevation gradients in Liziping Nature Reserve during June and July 2012. The results indicated that giant pandas there mainly fed on new shoots of B. spanostachya in this season. For B. spanostachya and Y. lineolata,biomass of their stems is greater than that of branches,and then followed by leaves. For single culm,biomass of Y. lineolata is greater than that of B. spanostachya. addition,biomass of perennial bamboos is greater that of biennial ones,followed by annual ones. Statistic models were constructed to predict biomass of single culm for Y. lineolata and B. spanostachya through their basal diameter.The above results can not only be helpful for understanding the optimal foraging strategies of wild giant pandas,
but also to calculate the total biomass of the staple-food bamboos for giant pandas in the reserve.
