摘　　要：本文采用改进单纯形法拟合了福建省中心产区杉木人工林8参数Richards多形地位指数曲线模型．精度验证的结果表明，所拟合的模型符合精度要求．对不同地位指数优势高生长特性进行了分析，结果表明：地位指数越高，则林分优势高速生期来得越早，生长潜力也越大．In this paper, Modified Simplex Method was used to establish the Chinese fir polymorphic siteindex model, with 8 parameters of improved Richards function, in central growing area of Fujian, The resultof precision test showed that the model precision is desired. The dominant height growth characteristics of different site index were analysed. The result showed that the higher the site index, the earlier the fast growingperiod of dominant height comes, and the greater its growing potential.
