摘要
树木高度是评价其立地质量和生长状况的重要依据。提出了两种基于激光测距的树高测量方法,介绍了激光测量树高的工作原理及测量精度计算方法,通过对比阐明本研究所采用的测量方法在理论上可行,在实际测量中可避免因障碍物阻隔而引起的测量误差,具有很好的实用性。
Tree height is a significant basis for the estimation of site quality and forest growth. Two laser distance-based methods for measuring tree height are presented and working principle of laser measuring tree height and measurement precision calculatin methods are introduced. Through comparison, the theoretical feasibility of the measurement methods adopted by the center is stated, avoiding the measurement errors caused by obstacles in the actual measuring process , therefore having very good practicability.
