摘　　要：复杂森林环境和障碍条件下植物高度及距离测量是林区测量的难题。通过4个点倾角测量,2个点水平夹角测量,得出走向困难地段物体的高度及物体至观测点之间的水平距离,同时利用经纬仪进行高和水平距离测量。试验证明,经纬仪的测高、测距相对误差分别是此方法的2倍、3倍,表明该测量方法可行并有一定的优势。The measurements of plant height and distance under complex forest environments and barrier conditions is a difficult issue in the forestry measurement. In this paper, a new method was introduced, the height and distance were obtained by measuring the four inclination angles and two horizontal angles. The conventional measurement by theodolite was also compared. The results showed that the relative errors of the conventional method for the height and distance measurements were 2 and 3 times higher than those of the new method, indicating the feasibility and advantages of the new method.
