| Abstract: | The reason for simulating DBH and height of trees using GAM model is described. Combining the measured data, GM （ 1,1 ） and GAM （ 1 ） were used to simulate the DBH and height growth of Pinus yunnanensis in the middle region of Yunnan province. The results show that GAM （ 1 ） has the higher precision and more important using value. |
