The method of modified simplex was applied to optimize the models, and the fitting results show that liu - logistic model was more suitable than logistic model to the actual growth trend of form. taxus chinensis var. mairei population, and the highest growth rate of basal area was the tenth age class, namely the phase when breast diameter was 68 ~ 76 cm
以胸高斷面積代替種群生物量，分別採用logistic常規模型及劉金福提出的logistic改進模型對南方紅豆杉種群的增長動態進行研究，運用改進單純形法對模型進行優化，擬合結果表明改進模型比logistic常規模型更符合南方紅豆杉種群的增長趨勢，南方紅豆杉種群的最大增長速度出現在第10齡級，即胸徑為68 76cm時期。 -
