蓄积量角规是在断面积角规基础上发展起来的一种测树工具。用蓄积量角规可直接测定林分每公顷蓄积量。它具有精度高、速度快、操作简便、制造容易等优点。内蒙古自治区林业勘察设计大队设计了一种有四个蓄积量系数的钢卷尺式的蓄积量角规,经过十几年的生产实践,证明是一种较好的测树工具,受到测树人员的好评。这种工具不仅适用于林区森林资源调查,也可用于伐区调查、抚育采伐等作业设计。为了与兄弟单位 Volumetric angle gauge is a measure of tree tools developed on the basis of the sectional area angle gauge. With the accumulation of angle gauge can be directly measured per hectare volume of forest. It has the advantages of high precision, fast speed, easy operation and easy manufacture. Inner Mongolia Autonomous Region Forestry Investigation and Design Brigade designed a four-volume volumetric steel volumetric volumetric angle gauge, after more than 10 years of production practice, proved to be a good tool for tree measurement, tree-testing by the staff Praise. This tool is not only suitable for forest resources survey, can also be used for cutting areas, deforestation and other operations design. For brotherhood with
