用二次幂非线性微分动态预测了杉木、云杉、落叶松三树种胸径(树高)平均生长量,反映不同树种树木的平均生长过程,是用来预测树木平均生长量较为理想的动态模型。
The average growth of DBH (tree height) of three kinds of Chinese fir, spruce and larch was dynamically predicted by nonlinear differential of quadratic power, which reflected the average growth of trees in different species and was the ideal dynamic model for predicting the average growth of trees .
