摘要
采用加权最小二乘法拟合模型,对拟作为贵州省马尾松人工林地径材积式的两个数学模型进行各项评价指标的对比分析和适应性检验,以确定马尾松地径材积最佳模型,为贵州省森林资源管理提供计量依据。
By adopting the weighted least square method, the comparation analysis and adaptability test to the different evaluation indexes for two mathematical models which is planned to be Pinus massoniana plantation rhizome volume formulas in Guizhou Province are made, with the aim to determine the optimal models of Pinus massoniana rhizome volume. It will provide the measuring basis for forest resource management of Guizhou Province.
