为了解抚育间伐对华北落叶松生长的影响，采用树干解析的方法对抚育间伐前后的华北落叶松胸径生长量及单株材积生长量进行了对比分析，结果表明，抚育后优势木和平均木的胸径年平均生长量分别为抚育前的2．20和2．00倍，单株材积年平均生长量分别为抚育前的2．78和2．90倍；被压木抚育间伐前后的胸径年平均生长量分别为0．26 cm 和0．32 cm ，单株材积年平均生长量分别为0．0016 m3和0．0031 m3，抚育采伐明显促进了华北落叶松林木的生长。

Abstrct :In order to understand the effect of thinning on the grow th of DBH of L arix p rinci‐pis‐rup prechtii ,contrast analysis on diameter grow th of L arix p rincipis‐rup prechtii before and after thinning was conducted .The results showed that the annual diameter grow th of the dominant trees and the average trees after thinning was 2 .20 and 2 .00 times as high as before thinning ,and the annual average individual volume of dominant trees and the average trees was 2 .78 and 2 .90 times as high as before thinning .But the annual diameter growth of sup‐pressed trees was 0 .26 cm and 0 .32 cm respectively ,with the annual average individual vol‐ume of 0 .001 6 m3 and 0 .003 1 m3 .It was concluded that thinning can raise the growth of L arix p rincipis‐rup p rechtii .
