备注

多功能测树仪是集多种测树功能于一体的测量工具。根据三角函数原理,结合传感器技术和计算机技术,将高度、距离、方位角、坡度、两点高差、立木任一部位形率等数据测量功能集于一体,并成功研制数字式多功能测树仪。测量方法适合在复杂森林环境中测量,解决了复杂森林环境植物高度及距离测量和树干中央直径及胸高形率测量难的问题,能够满足一般森林资源调查的精度要求,效果良好。

Multi-functional dendrometer is a kind of forestry tool that can measure multiple factors of forest. By combined sensortechnology and computer technology,a digital multi-function dendrometer has been developed,which integrated the functions ofmeasuring height,distance,azimuth, slope, elevation, form quotient of any parts of the stem into one body at the same test. Thedendrometer can fit the complex forest environment, solved the difficult problems in aspects of plant height, measure distance, centraldiameter and form quotient of breast height. The accuracy can meet the requirements of general forest survey.
