| 摘 要： | 根据光皮桦天然群落样地调查资料,选择平均木进行树干解析。研究结果表明：光皮桦的胸径、树高、单株材积生长均可采用Schumacher（苏玛克）方程Y=ae-b/t进行较好拟合,并由此推导其胸径、树高和材积生长的成熟年龄分别为第47年、40年和102年。本研究为进一步了解光皮桦生物学特征和人工林经营提供理论参考。 |

| Abstract: | Based on investigation of Betula luminifera commnity in Jiulianshan National Nature Reserve,trunk of standard trees was chosed to analyze the growth regularity.The results showed that the DBH,height and volume of B.luminifera could be fit by Schumacher model（）.And the fully grown age of DBH,height and volume was 47 a,40 a and 102 a,respectively.This study would be a better understand and reference for this promising species. |
| Keywords: | Betula luminifera Growing regularity Jiulianshan National Nature Reserve |
