Studies On The Distribution And Biomass Of The Bamboo Of The Fargesia As The Main Food Of Giant Panda In Foping And Changqing Reserve

Based on the survey of transects and plots, the distribution and biomass of two species of bamboo, Fargesia qinlingensis and Fargesia dracocephala, as the main food of giant panda in Foping and Changqing National Nature Reserve were studied. The main results are highlighted in the following:1. According to the result of the field survey, F. qinlingensis is distributed in higher altitude and F. dracocephala is distributed in lower altitude. The distribution map of the bamboos is made by GIS.2. It can be summed up that the regress model of biomass about two bamboo: The regress model of biomass about F. qinlingensis is W=0.8101(D²H)^0.8311. The regress model of biomass about F. dracocephala is W=119.3416D^189.3647H^41.9312.3. Based on 44 plots about F. qinlingensis is showed that the biomass in 1m² is 4.1621 kg in Foping and 2.8923 kg in Changqing. Based on 11 plots about F. dracocephala is showed that the biomass in 1m² is 4.0257 kg in Foping.4. Based on the percentage of the bamboo area, the total biomass of F. qinlingensis is 334052.1 t in Foping and 91732.9 t in Changqing. The total biomass of F. dracocephala is 14855.52t in Foping.5. The bamboo resource is not the main factor to restrain the development of the giant panda species in Foping and Changqing National Nature Reserve.
