Spruce stands diameter structure of artificial origin

This paper analyzes the structure of spruce stands of artificial origin according to natural diameter class. There have been found that the coefficient ofvariation and skewness of trees line distribution according to natural diameter class of spruce stands of artificial origin decreases maturing. It is revealed that a line of distribution according to natural diameter class in mature spruce artificial origin is more compact than in the spruce forests of natural origin. There have been found that the 5th grade spruce crops in three central natural levels are thicker than stands of natural origin by 11.6%
