Second, a little change is made in Christen hypsometer, but the operating way remains unchanged, and the precision of observation value is increased by 100 times, with 231 more observation values obtained. The hypsometer altered in this way has the proofread function. 对克里斯登测高器只作简易变更,用法不变,即可使观测值精度提高100倍,观测值增加231个,且具有校核作用。
Forest hypsometer is the common tool widely used in studies of forest management, forest resources survey, the use of forest harvesting, forest carbon sequestration estimates, and many other technical fields. 森林测高器是林业行业的基本工具和常用工具,广泛应用于森林经营研究、森林资源调查、森林采伐利用、森林碳汇测算等诸多技术领域。
