Abstract: Because the tree-crown of mean wood assortment in China are obviously greater, the numbers of trees in a stand are counted by projected areas of tree-crown of dominant trees, the trees above mean trees and double indexes, mean trees, all trees of a stand (N=10000/(π/4)(CWD)2, CWD--diameter of tree-crown). Except special kinds of trees, the numbers of trees are different greatly with greatest density of stand. Form the above, the conclusions can be drawn: It is lack of fully theoretical bases that the numbers of trees counted by projected areas of tree-crown are as greatest density of a stand.
Key words: Greatest density of stand, Projected areas of tree-crown
