Through comprehensive analysis of the Betula luminifera traits and woodland environment,we analyze and contrast the effect of the growth,according to the different planting density, by means of the analysis of the growth effect for the tree height, diameter at breast height, growth effects of the volume per unit area ,as aresult analysis of variance we can get the growth effect of Betula luminifera height of different planting density is very obvious.
Diameter at breast height variance of different planting density is significant.
The greater the silviculture density is ,the better the growth condition of Betula luminifera is.
The greater the distribution of volume per unit is,the better it is for improving the efficiency of forestry and forestry production.
