| 摘 要： | 以150株西藏高原林芝云杉解析木资料为样本，利用Excel2003软件中的5种数学模型对林芝云杉的树高与胸径异速生长的进行建模，并分析其精度；结果显示幂指数方程H=1．68D0.777拟合效果最佳（R2=0．981）；该模型可用于西藏高原东南部快速准确地测算林芝云杉平均树高，也可为计算立木材积、编制出材率表和评价林分的立地质量提供基础数据，对于了解林芝云杉生长状况和指导当地林业生产具有重要作用。

| Abstract: | In this paper, five height-diameter allometric growth equations were evaluated by making use of Ex- cel 2003 software, based on the data of 150 parse trees of Picea likiangensis var. linzhiensis in Tibet plateau, and every equation＇s accuracy was analyzed, the results showed that： The exponential equation （H = 1.68D0.777） was the best fit （R2 = 0. 981 ） , it can be used to calculate the average tree height of Picea likian- gensis vat. linzhiensis in southeastern Tibet plateau precisely and rapidly , and can provide the basic data for the calculation of tree volume, compilation of merchant volume table and the evaluation of forest-site quality, which is very important for understanding the growing status of Picea likiangensis var. linzhiensis and guiding forestry production. |
