Relationship between Density and Mean DBH of Pinus sylvestris var.mongolica plantation in Honghuaerji Sandy Land
Based on the statistical analysis of the density and DBH of Pinus sylvestris var.mongolica in 25 natural plots of Honghuaerji National Forest Nature Reserve,result shows that the plant area (N)and the average DBH (D) have the relationship of power function,which reach pole significant level (R =0.998),and the fitting equation is N =24 703 D-1.22.The slope efficiency of the fitted equation is-1.22,which is a difference from the standard slope (b =-1.605) of Reineke L.H,which may be the result of natural fire and human disturbance.
