Stand in different growth period by weibull distribution function.(6) Height and diameter of a tree are two factors to show growth in upright and cross. When they are young, the ratio of height and diameter is more than 1. It shows the fact that natural stand, especially natural sprout forest grows fast in early period. Later, with the age increasing, the ratio of height and diameter gradually reduces. In nearly mature stand and mature stand, increment of diameter is over increment of height.
