| 摘 要： | 应用灰色系统理论中的GM(1,1)模型和Verhulst模型,分析了马尾松在河南省不同立地条件下的生长过程。结果表明:马尾松前期生长为指数曲线,后期生长为对数曲线,全期生长为S型曲线;马尾松生长状况与速生期随立地条件而不同。

| Abstract: | Analyses the growth patterns of Pinus massoniana under different site conditions in natural distribution range of Henan Province by GM (1,1) and Verhulst models of grey system theory. The results indicated that an exponential growth curve was obtained in the early growth stage and a logarithmic growth curve in the later growth stage. In the whole growth periods, a "S" shaped growth curve was obtained. The growth condition and accelerated growth stage of P. massoniana varied with the site conditions of the range. |
