| Abstract: | Advanced parallel line method was applied to fit the density effect model on basis of screening information on 188 temporary sample plots. Meanwhile the accuracy of the model was tested. The result showed that the average predicted accuracy was above 90%. So this accuracy coincided with model test standard. |
