摘要
本文提出了用经纬仪测量立木高、径元素的原理和方法,论证了利用TDJ6型经纬仪所能达到的理论精度,并与直径的实测精度进行比较,证明该方法可行且提高工效4倍以上。
This article put forward the principle and the method to sur-vey height and diameter of a tree with theodolite, demonstrated theoretical precision reached using TDJ6-theodolite, compared with practically survey-ing prfcision, proved that the method is available and can increase efficie-ncy more than 4 times.
