摘要(Abstract)：
林木直径是森林计测中的一项重要因子,同样也是评价立地质量和林木生长状况的重要依据。本文简要阐述林木直径测量方法在森林调查和森林计测中的应用以及国内外的研究现状,并充分探讨了树木直径测量方法所代表的测量仪器的原理、结构和测量误差。同时也对各种测量方法各自的优缺点进行了比较。从而为森林调查和森林计测中能更精确、更有效的测量林木直径提供理论参考。
The diameter of trees is not only an important factor in forest measuration,but also the important basis evaluation for forest tree growth and site quality. The application situation was elaborated about the diameter measurement method of trees in forest investigation and measuration at domestic and aboard.Discussion was made on the principles,structures and measurement errors of measuring instruments represented by tree diameter measurements. At the same time,the advantages and disadvantages of various measurement methods were compared. Accordingly,this paper could provide theoretical reference for improving the measuring accuracy and efficiency of the tree diameter in forest investigation.
