Abstract: Shennongjia is the east edge for the distribution of Fargesia spathacea, where the forests are largely distributed over mountain slopes at the altitude of 1200—2000m.Fargesia spathacea has a strong ability of asexual propagation and regeneration, its life-span being about 7—8 years. The regression equations between weight and height and between height and diameters are respectively Y=-95.667+1.131X and Y =23.172+0.576X. The weight percentage of 1,2 and 3 years plants can reach to 27.15%, 27.97% and 44.88% respectively. The total reserve of Fargesia spathacea in Shennongjia is about 500000 tons, which is rich in nutrients and provides ideal food resources for panda.
