摘要
根据１００块标准地材料，利用１００株平均木解析木，探讨了杉木人工林生物量与胸径（Ｄ）、树高（Ｈ）及林木各部分生物量，总生物量与材积（Ｖ去皮、Ｖ带皮）的回归关系，选出了Ｄ、Ｈ与各器官生物量之间相关最密切的方程及材积与生物量的最佳估测模型，初步研究了生物量与林龄、地位指数和密度三者之间的相关关系。
One hundred Chinese fir plots(n=100)were measured in
QinyuanCounty of Zhejiang Province.One hundred average trees from each of theplots were
analysed.A series of regression equations were developted for(1)total biomass,(2)stem
biomass,(3)shoot biomass,(4)leave biomassand( 5)root biomass with(1)DBH(D)and
height(H)or(2)volume(V)asindependent variables.The correlation coefficients of biomass to
stand age,density and site index were determined.discussion of all retults was presented.
