贵州省人工马尾松立木材积和地上生物量方程研建OA北大核心CSCDCSTPCD
Establishment of Tree Volume and Aboveground Biomass Equations for Masson Pine Plantation in Guizhou Province
以贵州省人工马尾松样木的立木材积和地上生物量数据为基础,建立省级总体平均模型和以区域作为特定参数的哑变量模型及线性混合模型,并对中心区和一般区2类区域性模型与省级总体平均模型之间的差异进行对比分析和预估效果检验.结果表明:对立木材积和地上生物量估计而言,区域特定的模型与总体平均模型之间以及哑变量模型和线性混合模型之间并没有显著差异.本文所建模型为贵州省马尾松人工林的蓄积量和生物量监测评估提供计量依据,所用方法为建立其他含特定参数的通用性模型提供可行途径.
Based on the tree volume and above-ground biomass data of Masson Pine (Pinus massoniana) plantation of Guizhou Province in China, population average models for province-level estimation and region-specific dummy variable models and linear mixed models were established at first. Secondly, the differences between two specific models for central region and other region and population average models were compared and analyzed, and the predictions of various mode…查看全部>>
