改进每公顷立木蓄积量的测定技术,是森林经理中的一个重要问题。目前各种测定方法的基本原理是测树学中常用的下列公式:V=∑gHf_(1.3)式中:V—每公顷立木蓄积量,∑g·每公顷立木断面积总和,H—平均高,f_(1.3)—形数。总断面积及平均高,可用测高器和根据比特里西原理制作的角规 Measuring techniques to improve stock volume per hectare is an important issue for forest managers. At present, the basic principle of various determination methods is the following formula commonly used in tree measurement: V = ΣgHf_ (1.3) Where: V-stumpage per hectare Σg · sum of stump area per hectare H-average height , f_ (1.3) -shape. The total cross-sectional area and average height, available height gauge and according to the principle of bit Li West produced angle gauge
