Abstract: In this paper, the authors present three types of tree-crowns upon the eccentric growning of standing trees, i. e. normal crown, sway crown and eccentric crown. As indicated above, a cross-measuring method of the tree-crowns is designed with regard to aspect. A 4m² square control is developed in posting a standing tree as well. It is obvious that the precision and repetition of the methods are much better in tree measurements.
