摘要:
 利用地基激光扫描技术采集了泗洪县陈圩林场中4块样地178株杨树的2期点云数据，对其进行干形变化分析。首先建立试验形率与胸高形数的估测模型，然后将(h+3)/2引申到树木干形分析中，定义TAP和TAP累积量，尝试用干形指标描述2期TLS数据的不同造林密度下杨树干形变化，最后对研究区整体干形变化进行分析。结果表明，试验形率可有效估测胸高形数，R2为0.773，RMSE为0.37%；TAP累积量和材积变化量随造林密度增加而降低，高径比变化量随造林密度增加而增加；研究区整体树木削度减少，材积增加，干形趋于通直圆满。因此，相较于传统干曲线严谨复杂的计算方法，TAP累积量的计算更加方便易算，用以代替连续的曲线方程，可以近似描述树木干形变化，为后续干形变化研究提供了新的思路。
Abstract:
 In this study,using ground-based laser to scan 178 poplar trees in 4 plots set in Chenwei Forest Farm in Sihong,Zhejiang Province the data of 2-phase ground-based laser point cloud were obtained.With the help of RiSCAN Pro to pre-process the data,to extract tree height,diameter of each part and other tree measuring factors,the shape parameters were modeled,and the trunk shape changes of four different planting densities (row spacing of 6 m×6 m,4.5 m×8 m,5 m×5 m,3 m×8 m) were compared.The main research results were as follows:1) design the concepts of experimental shape rate,the accumulation of TAP per unit area.An index system with (h+3)/2 as the core is established to evaluate the change of tree stem shape.2) Through the comparative analysis of the changes of tree trunk shape and volume under different planting density in the two periods,it is found that the growth of trunk shape and volume is the best under the condition of 6 m×6 m.The growth rate of volume is 17.37%,and the accumulation of TAP per unit area is 100%.The index system with (h+3)/2 as the core is established in order to provide new ideas and technical guidance for the follow-up tree stem shape analysis.
