摘　　要：树高的精准测量是森林资源经营和管理的一项基础工作,也是评价立地质量和林木生长状况的重要依据。实验中利用测高器、罗盘仪、经纬仪和全站仪等仪器测定了7个不同树种的树高,阐述了其测量的原理与过程,并构建了树高精准化测量的模型。根据30组不同树种的树高测量数据进行对比和分析,得出树高自动精准测量的结果:全站仪的精度最高,其次是经纬仪和罗盘仪,最后是测高器。采用相同的仪器测量不同树种的树高,其精度也不同。树干笔直、树冠简单的树种精度较高;针叶树种也比阔叶树种精度高。构建的树高测量模型,为实现林业调查的自动化和精准化提供了理论依据。Tree height measurement precision operation and management for forest resources is a basic work,but also the important basis of evaluating the site quality and tree growth conditions. Altimetry device,compass, theodolite and total station and other equipment were measured 7 different species of tree height,which described its measurement principle and process, and constructed trees for high-precision measurementmodel. The 30 groups of three for different species according to tree height measurement data comparison andanalysis, the tree height automatic precision measurement results： the highest precision total station, theodoliteand compass followed, and finally the altimeter device. Using the same instruments to measure differentspecies of tree height, its accuracy was also different. Trunk straight, simple tree canopy had a high accuracy;conifer species than the broadleaf species with high accuracy. The author built the tree height measurementmodel forthe realization ofthe automation and precision forestry survey had provided a theoretical basis.
