| 摘 要： | 以云南省金沙江流域永仁县的云南松天然次生林优势木胸径为研究对象,选择Logistics、Gompertz、Richards、Korf、Levakovic、严格苏马克和Hossfld模型对其进行拟合.通过对总相对误差、平均相对误差、平均相对误差绝对值和预估精度的分析,从中选出最优生长模型.研究结果显示,这些生长模型对云南松天然次生林优势木胸径生长拟合的精度基本相近.最优生长模型为Gompertz模型. |

| Abstract: | Taking dominant tree DBH of secondary Pinus yunnanensis forest of Jinsha River watershed within Yunnan province as objectives,models of Logistics,Gompertz,Richards,Korf,Levakovic,Johson-schumacke and Hossfld were chosen to fit.The best growth model was selected,by applying the analysis of the total relative error,the average relative error,the average absolute relative error and the estimate precision.The result showed that simulative precision of these growth models were similar.Gompertz model was the best... |
