摘要
研究了杉木人工林相对树高曲线基本模型及参数扩展模型，提高了相对树高曲线模型估测精度，初步探讨了树高曲线与林分特征因子间的关系以及“标准树高曲线”设想的局限性。
Simple models and expanded parameter models of relative tree height of Cunninghamia lanceolata even stand were studied.The model predict precision of relative tree height was improved.The relation between models of tree height and stand characteristic factors was analyzed.
