| Abstract: | 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. |
