Abstract:A forest‘s productivity can be optimized by the application of rules derived from monopolized circles. A monopolized circle is defined as the circle whose center is a tree and radius is half of the distance between the tree itself and its nearest neighbor. Three characteristics of monopolized circle were proved. (1) Monopolized circles don‘t overlay each other, so the nearest relationship is tangent. (2) “Full uniform pattern” means that the grid of a×b=N trees cover the whole plot, so that the distanc...
