| 摘 要： | 利用样木资料,以胸径D、树高H为自变量,材积V为因变量,在多种二元材积模型筛选的基础上,选择山本公式建立木荷二元材积模型并用改进单纯形法进行优化,由此求得木荷二元材积模型为:V=0.00006801D1.865613H0.918129。该模型理论值和实际值差异不显著,实际应用误差小,精度高,完全能够满足生产上的精度要求,可在森林资源清查中推广应用。

| Abstract: | The study used data of sample trees,and tree diameter at breast height(D) and tree height(H) as the independent variable,and the timber volume(V) as a dependent variable.After many kinds of dual timber volume models were referenced,dual timber volume model of Schima superba was abtained:V=0.00006801D~(1.865613)H~(0.918129),which based on Yamamoto(山本) formula and the optimization of improved simplex method.After the model was tested,the result showed there was no significant variation between theory and actual date,small practical application error,and high precision.The precision is eligible to be used in production and forest resources inventory. |
