摘　　要：针对我国森林资源调查监测手段落后的局面,研究开发一种机械式电子森林罗盘仪,以实现样地周界、树高和林木坐标等的测量。通过对比机械式电子森林罗盘仪、布鲁莱斯测高器、森林罗盘仪和手持激光测距仪等常用仪器测量结果的分析,结果显示:机械式电子森林罗盘仪的测量方位角、高度和水平距的准确度分别为0.30°、0.03 m和0.06 m,精密度分别为0.30°、0.94 m和3.53 m,方差分别为313.60、1.12和17.97,标准差分别为17.71、1.06和4.24,S值分别为310.50、1.12和18.05,机械式电子森林罗盘仪的各项测量结果都要更优。机械式电子森林罗盘仪的研制为我国“天地空”森林资源立体化监测体系,特别是地面调查手段更新探索了新途径。For the backward of forest resources investigation and monitoring in China, a mechanical electronic forest box compass was developed to measure sample plot perimeter, tree height and tree coordinates. Comparing with mechanical electronic forest box compass, Blume-less hypsometer, forest compass and handheld laser rangefinder, the results demonstrated that the accuracy of mechanical electronic forest box compass in measuring azimuth, height and horizontal distance was 0.30°, 0.03 m and 0.06 m, the precision of mechanical electronic forest box compass in measuring azimuth, height and horizontal distance was 0.30°, 0.94 m and 3.53 m. The variance of mechanical electronic forest box compass in measuring azimuth, height and horizontal distance was 313.60, 1.12 and 17.97, the standard deviation of mechanical electronic forest box compass in measuring azimuth, height and horizontal distance was 17.71, 1.06 and 4.24, and the S value of mechanical electronic forest box compass in measuring azimuth, height and horizontal distance was 310.50, 1.12 and 18.05, respectively. The measurement results of mechanical electronic forest box compass were the best. The development of mechanical electronic forest box compass would explore a new way for the three-dimensional monitoring system of forest resources, especially the updating of ground investigation instruments.
