杉木林分蓄积量不同测定方法的比较

Comparison of the Different Measurement Methods of Stand Volume

以同一块杉木林分为对象 ,对 9种常用的林分蓄积量测定方法进行对比分析 ,提出了在不同条件下的最佳测定方法 :无测树用表或相关数学模型时以等株径级标准木法较好 ,测树用表或数学模型齐全时最好采用形高表法 .

According to the comparable analysis of nine kinds of measurement method of stand volume on the same China-fir forest,this article provides the optimal methods in different application conditions. If there are no measurement tables or mathematical models, the method of equal number diameter class is the optimal way; otherwise, the optimal way is the method of form height table.
