Abstract: The Mongolian pine(Pinus sylvestris var.mongolica) is broadly introduced to sandy lands in north China,because of its good ecological adaptation. The Champan-Richards growth model is used to simulate the growth of diameter at breast height (DBH), height and volume of single tree in Honghuaerji and Zhanggutai regions. The results indicate that the quantitative maturity age of natural Mongolian pine forest in Honghuaerji is 100 years old and that of plantation in Zhanggutai is 46 years old, and that the fast-growing period is longer in Honghuaerji than in Zhanggutai.
