A Study on the Out put of Stand of Pine massoniana Plantation
【摘要】 提出了林分材种出材率表研制的基本原理和方法 ,采用现场实际造材样木建立了单株二元材种出材率模型 ,配合二元材积方程、 Weibull分布、相对树高曲线模型 ,编制了马尾松人工林林分出材率表
【Abstract】 This paper puts forward the cardical principle and method of studying the out put of stand wood category, establishes the model of single out put of general wood category according to the materials of actual bucking of sample trees on the spot, and draws out the out put of stand of Pine massoniana plantation coordinating the general volume equation, Weibull distribution and the relative diameter height curve
