| Abstract: | 47 analytical trees in the standard plots of the man-made evenaged pure stand of Larix Kaempferi in the western Henan mountainous areas have been studied. A mathematical model was set up with computer according to the standing form-factor.Based on the model,the relationship between form-factor,locality index and tree age has been discussed comprehensively. |
| Keywords: | Larix Kaempferi standing form-factor double-curve model multiple linear regression |
