The trunk runoff is decrease gradually with tree diameterbreastheight increased, the crown cover areas enlarged and the bark thickened.
树干茎流量随着林木胸径的增加、林冠覆盖面积的增大和树皮增厚而减小。

Result showed that different waterlogging depths have obvious effects on tree height, diameter at breastheight, under branch height, trunk morphological structure, stem base form, and growth process.
结果表明：不同水分条件对池杉的树高、胸径、枝下高、干形、树干基部形态及生长过程均产生明显的影响。

Factors involved in the model are: tree height. diameter at breastheight. bark thickness at breast height. height of first dead branch and height of blackened trunk.
