| 摘 要： | 本文试把灰色系统理论应用于林木生长量预测,探索其生长的灰色动态模型。建模时,桉树木生长的生理规律,采用了灰色校正模型。该模型使用呈指数规律变化的校正系数,克服了中长期预测误差较大的缺陷,从而扩大了灰色预测方法的应用范围。最后,利用生成的预测校正模型对未来经理期的生长量作出预测,与实际情况吻合较好。

| Abstract: | This paper attempts to apply the theory of grey system to forest growth prediction and seeks the grey mobile model. When creating the model, the rectified grey model was used according to the physiological law of forest growth. This model is especially suitable to the occasion that the change takes place in system interior. Therefore the scope of grey prediction was extended. At last, the forest growth of coming management-period was forecasted by the rectified grey model. The result corresponded closely to objective reality. |
