Abstract: The biomass of Bambusa textilis var. tasca was studied using regression models that were constructed for biomass components:bamboo pole-dry (Bt),bamboo leaf-dry (Bf),bamboo culm-dry (Bs),aboveground part-dry (Ba),and bamboo-dry (Wbt);based on diameter at breast- high(DBH)(D)and the average thickness of the culm-base(A). For the purpose of Bambusa textilis var. tasca rational operation and development to provide theoretical basis and basic data. Results showed that culm biomass of B. textilis var. tasca counted for 74.62%,which was much higher than Phyllostachys pubescens. Regression equations in terms of DBH were:Bt = - 2 672.765 + 1 299.919D + 59.298D2 -36.222D3,Bf = -2 756.615 + 1 290.910D + 95.822D2 - 34.991D3,Bs = -4 016.535 + 2 161.650D + 21.755D2 - 45.453D3,Ba = -7 445.916 + 3 952.480D + 45.439D2 - 96.666D3,and Wbt = -7 360.122 + 3 933.155D + 41.158D2 - 93.171D3,and in terms of A were:Bt = -1 914.129 + 739.465A + 30.261A2 -61.285A3,Bf = -3 342.800 + 1 228.745A -1.165A2 -104.356A3,Bs = -6 103.838 + 1 790.994A + 44.430A2 - 13.674A3,Ba = -9 770.036 + 2 464.708A + 19.688A2 -23.782A3,and Wbt = -9 914.842 + 2 912.175A + 25.624A2 -23.513A3. With these equations,Bambusa textilis var. tasca had an average yield in stem biomass of 1.52 kgplant-1;an average biomass bamboo of 2.31 kgplant-1;a stem biomass per unit area of 3.28 kgm-2;and a bamboo biomass of per unit area of 4.96 kgm-2. View of the high yield of Bambusa textilis var. tasca,wood is better features,both for the development of Bambusa textilis var. tasca ease the current difficulties facing the bamboo industry,or the use of bamboo species diversity has important economic and ecological significance.[Ch,8 tab. 29 ref.]
