The technique is based on allocation of areas in which each tree has the domination in spatial sharing of a resource. The study used data from three permanent research plots even-aged pine stand based in Krasnoyarsk sporadic forest-steppe. For a studied stands close dependences of diameter of a trunk of trees and crown projection area on the area of their DA are established.
