| 摘 要： | 通过实测 97株凹叶厚朴样木的地径和材积值 ,采用遗传算法、三次设计法、改进单纯形法拟合地径材积方程并与对数线性化最小二乘法进行比较。结果表明 :遗传算法、三次设计法和改进单纯形法拟合地径材积效果优于对数线性化最小二乘法 ,且 4种方法均能通过适用性检验。进一步建立了地径、胸径及树高之间的相互关系 ,为凹叶厚朴人工林的经营提供理论依据 |
| 关 键 词： | 凹叶厚朴 遗传算法 三次设计法 改进单纯形法 |

| Abstract: | The results show that the effects of fitting the ground diameter volume by the genetic algorithms,cubic design method and improved simplex method are superior to the effect of fitting the ground diameter volume by the method of logarithmic linearized least squares,and the 4 methods all can pass the suitability test The correlations between the ground diameter,dbh and height are further built,which provides the theory bases for the Magnolia officinalis plantation management. |
| Keywords: | Magnolia officinalis genetic algorithms cubic design method improved simplex method |
