断面积及蓄积量标准表(以下简称标准表)主要用于测定林分疏密度及蓄积量。在森林经营及森林调查工作上具有很大的实践意义。我省由于缺乏各种森林调查用表,常给林分调查工作带来困难。在一般情况下,往往不得不采用关系较密切的因子来代替。如测定林分疏密度时常用郁闭度来代替;或在测定蓄积量时利用平均形数,如林业厅林业勘测队确定针叶树平均形数为0.50,闊叶树为0.45;或借用其他地区或其他树种的调查用表。如我们以往在进
Cross-sectional area and volume standard table (hereinafter referred to as the standard table) is mainly used for measuring the density and volume of the forest volume. In the forest management and forest investigation work has great practical significance. Due to the lack of a variety of forest surveys in our province, it often brings difficulties to the investigation of forest stands. In general, often have to use more closely related factors instead. Such as the determination of density of forest density often used to replace the canopy density; or in the determination of the amount of accumulation using the average shape, such as the Forestry Department forestry survey team to determine conifers average shape of 0.50, broad-leaved tree 0.45; or borrow other regions or Other tree species survey table. As we have been in the past
