摘要
通过详细阐述角规测树的基本原理及测树操作方法,根据经验总结角规测树时注意事项,并以调查数据为例,演算了角规控制检尺测算林分单位面积蓄积的方法。
The basic principle and operation method of measuring tree with angle gauge are described in detail.According to the experience,the matters needing attention in measuring trees with angle gauge are summarized.Taking the survey data as an example,the method of measuring stand volume per unit area by angle gauge is calculated.
