The concept and framework of the biomass model for main local broad－leaved species in Guangdong were put forward due to the significance of the model. 9 local broad－leaved tree species were used as modeling objects, which were divided into 9 biomass modeling population. The number of ele-ments for each population was 90, among them, 40 roots were logging and another 40 were stem analysis. 60 trees of the modeling sample were based on the average allocation of 10 diameters, and another 30 trees were based on the origin, which were both determined by the trees proportion of each diameter class in Guangdong continuous resource inventory. In this paper, the methods of field investigation, sampling, internal test and modeling technology for the biomass model in Guangdong were proposed.%从乡土阔叶树种生物量模型研究意义出发,提出建立广东省主要乡土阔叶树种生物量模型的思路与框架;确定以9个乡土阔叶树种为建模对象,共划分为9个广东生物量建模总体,每个总体建模样本单元数为90株,其中采伐树根40株,树干解析样本40株;建模样本的构成是在10个径阶平均分配60株的基础上,30株考虑样木的产地因素,根据广东省森林资源连续清查样地中样木各径阶的株数比例确定产地及径阶的分配株数;提出适合广东省生物量建模的外业调查及采样方法、内业实验测定方法以及建模技术方法.
