摘　　要：采用树干解析法获取3种不同生长势(优势木、中庸木、被压木)杉木的胸径、树高生长数据,利用ForStat的生长曲线模拟杉木的胸径模型和树高模型,结果表明,Richards生长曲线是分析杉木胸径和树高的适宜生长曲线;3种不同生长势的杉木胸径生长曲线和树高生长曲线均呈"S"状曲线,有较高的相关性。Two growth indices,including diameter at breast height（DBH）and tree height of Cunninghamia lanceolatatrees with 3different growth vigors（dominant,intermediate and suppressed trees）were measured by stem analysis method.ForStat growth model was adopted to simulate the growth models of tree height and DBH.It was found that Richards growth curve was suitable for the analysis of DBH and tree height.The The growth curves of DBH and tree height of 3different growth vigors of Chinese Fir were ＂ S＂ shaped curves,and had significant correlations were observed between them.
