摘  要:
在绿竹分布范围内设置样地142块,采伐标准竹368株,调查标准竹各器官的生物量;应用回归分析法,找出绿竹生物量与胸径之间的相关关系.选择教学模型Y=aDb建立了绿竹生物量估测模型,并运用改进单纯形法对模型参数a、b进行优化,得优化生物位模型;W=0.203890D2.224536,R=0.998,F=156,提高了估测精高,可做为绿竹分布区内生物量测算.

摘  要:
Sinocalamus oldhami is a fine and fast growing species of bamboo. With a view toestimating its stand biomass in certain site conditions, 368 culms of standard bamboo in 142 sam-ple plots were cut to determine the biomass of each organ. Then,using regressional analysis, amathematical modelW=aDb was derived, where the biomass is closely related to the diameter inbreast high. The parameters a and b were optimized with the modified simblex method, bringingforth the model as W=0. 2O389OD2. 224536 with the relative coefficient being 0. 998 and the F volumebeing 156.
