Based 0n the m0dular organism population theory and studied on the clonal population biomass structure of young Bashania fangiana after natural regenerati0n in the Giant Panda's habitat of W0long Nature Reserve, meantime,analyzed the relati0nship of population biomass and its environment conditions, the result sh0wed that the cl0nal population biomass of young B. fangiana was 495. 962 kg/ha, the order of organ biomass was as follows: stem> branch> ro0ts>leaf> undergroun - stem, the distributi0n laws of different age -class bambo0 biomasses showed the normal distribution pattem. the total biomasses of three - year bambo0, four- year 0nes, five -year ones and six - year ones were 362. 393 kg/ha and 80. 29 per cent; but the percentage 0f one -year bambo0 and two-year ones and seven-year ones 1 eight -year 0nes ` nine-year ones and ten- year ones were l2. 97% and 8.64% respectively. In three forest types, the hightest biomasses 0f B. fangiana was Tusga chinensis + Betula utilia - B. fangiana forest, the second was AUes faxoniana - B. Fangiana forest,T. chinensis+B. ablo-sinensis-B- fangiana forest; The clonal populati011 biomasses of B. fangiana was increased with the altitude between25OO and 3OOO metres,but it was declined above 3000 metres.
