摘  要：
为了解间伐对彰武小钻杨生长的影响，采用按断面积49.8%、35.5%、31.8%和对照4种间伐强度处理开展抚育间伐试验。结果表明：不同间伐强度的林分，在平均胸径、平均树高、平均胸高断面积和平均单株材积均有显著差异。12年生林分，间伐强度49.8%、35.5%和31.8%林分的平均胸径分别为对照的1.22、1.16和1.09倍，平均树高分别为对照的1.11、1.09和1.08倍；平均胸高断面积分别为对照的1.48、1.37和1.19倍，平均单株材积分别为对照的1.60、1.47和1.27倍。

摘  要：
In order to understand the effect of thinning on the growth of Populus × xiaozhuanica cv. ‘Zhangwu', a thinning experiment was conducted by four thinning intensities with the cutting area of 49.8%, 35.5%, 31.8% and the control. The results showed that there were significant differences in mean diameter at breast height, average tree height, average cross-sectional area at breast height and average individual volume of timber in the stands with different thinning intensity.In the 12-year growth stand with thinning intensity of 49.8%, 35.5% and 31.8%, the mean diameter at breast height was 1.22, 1.16 and 1.09 times that of the control, respectively; average tree height was 1.11, 1.09 and 1.08 times that of the control, respectively; average cross-sectional area at breast height was 1.48, 1.37 and 1.19 times that of the control, respectively; average individual volume of timber was 1.60, 1.47 and 1.27 times that of the control, respectively.
