摘要
树高是评定立地质量和林木生长状况的重要依据,是林业调查地的必测项目。在林业生产、森林调查、科学研究、编制林业数表和立木材积的计算等工作中,都需要对树高进行测量。本文主要介绍一种基于相似三角形原理测量树高的简便方法。
Tree height is an important basis to for the investigation of forestry land assessment of site quality and tree growth status, and it is a necessary data in the investigation of forest. In forestry production, forest surveys, research, preparation of forestry tables and determining the volume of standings. This paper describes an easy way to measure tree height based on the principle of similar triangles.
