树高测定通常采用普鲁莱氏测高器,近年来也有用光学测树仪测定立木树高的。但在山高坡陡的南方林区,林地下木繁多,加之小地形破碎,用普氏测高器测高比较麻烦,一是要在两个不同方向上量距,增加了往返时间和上下爬涉的体力消耗,费时费事;二是其仪器最小刻划值为0.5米,估测到分米较困难,特别 Tree height determination is usually used Prudence sounder, in recent years also useful optical tree measurement instrument tree height. However, in the steep southern slope of the mountain forest, woodland numerous, combined with small terrain broken, with Platts height gauge more trouble, one is to measure in two different directions, increasing the round-trip time and climbing Involving the physical exertion, time-consuming and laborious; Second, the minimum score of 0.5 meters of the instrument, it is estimated to be more difficult to decimeter, especially
