| Abstract: |
| The theory and method of GM(1,1) combined models of plant populations were introduced. Based on the time-serial data of density of Keteleeria davidana var. chin-peii population obtained from Qingyan town of Guizhou province, a density GM(1,1) combined model of the population was established and its predictive precisions were compared with those of the GM(1,1) and the parabola model. The results showed that the GM(1,1) combined model may be one of the more effective and convenient population dynamic models. |
