| 摘 要： | 对四川省美姑县滇杨树高、胸径、材积生长规律研究结果表明:滇杨有较强的生长适应性,25年生树高为29.56 m,胸径为49.4 cm,材积为2.243 5 m3;滇杨造林初期生长相对较缓慢,在10年生时树高和胸径连年生长量到达峰值,之后开始下降但仍保持较高的年生长量;材积连年生长量和平均生长量随着树龄的增大而呈持续增长趋势,25年生时,仍维持较快的增长速度;Logistic曲线对滇杨树高、胸径和材积生长动态有较好的拟合效果.

| Abstract: | The growth pattern of height,DBH and stocking volume of Populus yunnanensis in Meigu County,Sichuan Province were researched.The results showed that Populus yunnanensis had strong adaptability.The average height of 25-year-old tree reached 29.56 m,with average DBH 49.4 cm and stocking volume 2.243 5 m3.Populus yunnanensis.grew comparatively slowly at the early ages,but the annual DBH and height growth rates achieved the peak values around the 10(th) year.After that the annual DBH and height growth rates started to drop down but still maintained at high level.The annual stocking growth rate and the mean stocking growth rate kept increasing along with the age till 25 years old.The dynamic growth models of height,DBH and stocking volume of Populus yunnanensis were respectively formulated. |
