林业生产和科研工作中常常需要测定林分平均胸径、平均树高、蓄积量等因子。为了提高测量精度,在测树技术和工具上做了一些改进,如固定测径位置,改轮尺测径为围尺测径,变径阶整化为读取实际值等。但在过去简单的计算工具条件下形成的一些较粗糙的计算方法仍在继续沿用。随着计算工具的发展,尤其是微电脑的迅速普及,理
Forestry production and scientific research often need to determine the average diameter of the forest, the average height, volume and other factors. In order to improve the measurement accuracy, some improvements have been made in tree measurement techniques and tools, such as fixed diameter measurement, caliper caliper measurement for caliper, and variable caliber correction for reading actual values. However, some of the more coarse calculation methods formed in the past under simple calculation tools continue to be used. With the development of computing tools, especially the rapid popularity of microcomputer, management
