基于地基雷达数据构建红松人工林树高、枝下高及接触高模型OACSTPCD
Building Tree Height,Height to Crown Base and Crown Contact Height Model for Korean Pine Plantation Based on Terrestrial Laser Scanning Data
采用地面激光雷达(Terrestrial Laser Scanning,TLS)扫描10 块人工红松林所得到的数据,与实地调查数据相结合,构建红松树高曲线模型、枝下高预估模型与接触高预估模型,并建立联立方程组.首先,从所选择的 5 种树高曲线模型中,选择出拟合效果较好的 2 个模型作为联立方程组的备选模型.然后再从5 个枝下高基础模型中选出1 个拟合效果好,并且适用程度高的模型作为基础模型,运用再参数化和最优子集回归的方法将林分因子(林分平均胸径…查看全部>>
In this paper,data obtained by scanning 10 artificial Korean pine forests based on Terrestrial Laser Scanning(TLS),were combined with field survey data to construct tree height curve model,height to crown base prediction model and crown contact height prediction model,and a simultaneous equation system was established.First,from the five kinds of tree height curve models se-lected,two models with better fitting effects were selected as the candidate models o…查看全部>>
