| 摘 要： | 通过伐倒树木进行解析可以精准获取材积，但此方法除了劳力费时外，还对树木有着毁灭性伤害；而传统的几种估测立木材积的方法精度又得不到保障。随着测量仪器的快速发展以及当今对生态文明建设的高度重视，林业量测有了更为准确和严格的要求，本文提出一种基于全站仪量测树木材积的方法：通过采集树木的胸径、地径和全站仪与树干任意处左右两侧切线的夹角，根据区分求积法原理精准计算立木材积，将通过全站仪量测获取的树木材积值与伐倒该树木测得的材积值进行比较分析。数据表明：该方法量测材积精度高达93％以上，完全可以替代伐倒树木测量材积的方法。

| Abstract: | The tree′s volume could be obtained by felling the tree , while this method was time-consuming and needed a lot of labor , in addition , it brought devastating damage to the tree .For the stumpage , the traditional estimation methods had a low accuracy .With the rapid development of measuring instruments and the great importance to the ecological civilization construction , there is a more ac-curate and strict requirements on the forest measurement .In this paper , a method to measure the tree′s volume based on Total Station is proposed, i.e., the precision calculation of the stumpage could be made through sectional measurement principle by collecting trees’ parameters of DBH , ground diameter and angle between Total Station and bilateral tangent lines of tree trunk at any section . Then volume measured by Total Station was compared with felling trees , the results showed this method′s accuracy was up to over 93%, which could replace the traditional measurement methods . |
