| 摘 要： | 研究并分析了间伐前后及不同间伐强度林分结构的变化。利用三参数韦布尔函数模拟林分胸径分布，通过其参娄的变化进行定性分析。结果表明，以小径木为间伐对象的间伐作业对林分胸径分布有正面影响。对于林木生长，以中度间伐效果最好。

| Abstract: | Taking larch as example, the effects of thinning operations on stand structure and the changes of stand structure before and after thinning as well as the effects causing by different thinning degree wereanalyzed. The three-parameter weibull distribution function was used to describe the changes of duameterat breast height (DBH) distribution for each treatment, Then qualitative analysis was carried out based onthe changes of parameters. The results indicated that thinning based on small DBH had positive effect onstand distribution. Concerning the individual growth. the intermediate thinning has the best effect. |
