1 概述DQS～1A森林罗盘仪是一种新型多功能林业测量精密仪器。它不但可完成普通罗盘的一般林业测量,还可以量测可见树干任意部位的直径、树木的测高、立木材积测定和材种出材量调查等,其仪器的最大特点是无标尺测距、测高和测径,对育种工作的树种选优,固定样地的定位测量有很大的优越条件,能解决树木上部直径测量的困难,能准确、迅速得出结果。
1 Overview DQS ~ 1A forest compass is a new multi-functional forestry measurement precision instruments. It can not only accomplish general forestry measurement of common compass, but also can measure the diameter of any part of the visible trunk, the height measurement of trees, the determination of timber volume and the investigation of timber output. The most prominent feature of this instrument is the non-scale distance measurement, Height measurement and diameter measurement, the breeding of tree species selection, fixed sample positioning measurement has great advantages, can solve the difficulty of measuring the diameter of the upper part of the tree, can accurately and quickly come to the conclusion.
