| description | Nonlinear mathematical models were used to develop regression equation by relating the mean diameter square as a dependent variable and number of trees per hectare as the independent variable. As a result the nonlinear regression equation screened was
N=EXP (7.02906-0.03638 Dq)
The statistical characteristics of the nonlinear equations were:
R2=0.93 S.E=0.1099
The following equation could be used to find out the stand density index (S.D.I).
Log S.D.I=log N-0.005744 (DK-Dq)
When the number of trees per hectare, mean diameter square, mean diameter and age, were known. |
