Study on the affect of the crown-fullness ratio on the growth of the tree and the form of the tree-trunk
XU Cheng-li, Jinglan Zhang · Hebei Nongye Daxue xuebao · 2005
The crown is an important portion of a tree. Meanwhile, the quantity index-crown-fullness ratio is not only reflecting the state of growth space of trees, but also affecting the growth process of trees and the form of tree-trunk. The result shows the smaller the diameter, height, the trunk volume of the tree, the larger the crown-fullness ratio and the larger the diameter, height, the trunk volume of the tree, the smaller the crown-fullness ratio, therefore, the relation of the diameter, height, trunk volume of the tree and the crown-fullness ratio is in negative relation. The relation of the form factor and the crown-fullness ratio is in positive relation.
