摘　　要：护岸林是三峡水库能否起长久效益的一项重要保障措施 ,通过对三峡库区撑绿竹护岸林的调查 ,测定了撑绿竹生物量与竹高、胸径等林分因子 ,分析了它们之间的相互关系 ,采用线性回归、非线形回归和幂函数方程进行数学模型拟合 ,得出结论 :三峡库区的撑绿竹护岸林具有较大的生物量 ,生物量与胸径拟合方程为 W=1.346 3D0 .1674,R=0 .6 45 6 ;生物量与竹高拟合方程为 W=0 .174 5 H1.3 10 2 ,R=0 .994 1;单株总生物量随生长年限变化方程为 Y=1.36 88x0 .70 99,R=0 .9819。shelter-belt is an important measure that is pertinent to the long benefits of Three Gorges Reservoir. An investigation was made to measure the biomass, stem height, stem DBH, ect. of Bambusa pervariabilis×Dendrocalamopsis oldhami in the bamboo shelter belts of Three Gorges Reservoir Area. The interrelation ships between bamboo biomass,stem height and DBH were analyzed. Mathematic models used included linear regression and exponential function. The results showed that the Bambusa pervariabilis×Dendrocalamopsis oldhami shelter-belt had a high value of biomass.The fitted equation of biomass and DBH is W= 1.346 3D 0.167 4 (R= 0.645 6),and that of the biomass and height is W=0.174 5H 1.310 2 (R=0.994 1);The equation of individual plant biomass and age is y=1.368 8x 0.709 9 (R=0.981 9).
