| 摘 要： | 采用样带网格调查方法和群落重要值分析方法，研究透光抚育（全透光、半透光、未透光）对红松阔叶混交林群落（人天混群落）的树种组成结构、径级分布、蓄积量和红松蓄积生产力的影响效果。结果表明：沿由小到大的透光强度，人天混群落中红松重要值依次增大（0．499～1．000），透光有利于人天混群落中红松优势地位增强；红松大径木比例依次增加（0．00％～54．0％），小径木比例依次减少（74．9％～2．7％），透光有利于人天混群落中红松大径木比例提高；群落蓄积量依次增加（60．2475～230．4051m^3／hm^2），红松蓄积生产力依次增加（1．2692～5．3603m^3／hm^2·a），透光有利于人天混群落蓄积量及红松蓄积生产力的提高。 |

| Abstract: | The effects of crown thinning on tree species composition structure, diameter classes distribution, volume and volume productivity of Korean pine plantation communities were studied by using sample plot with net check survey method and community importance value analysis method. The results showed that importance value of Korean pine in plantation communities increased in tunas along with the crown thinning intensity increasing （0.499 ～1.000）, proportion of larger diameter classes increased in turns （0.0%～54.0% ）, proportion of smaller diameter classes decreased in turns （74.9%～2.7% ）, community volume increased in turns （ 60.2475 - 230.4051 m^3/hm^2）, volume productivity of Korean pine increased in turns （ 1.2692 - 5.3603m^3/hm^2·a）. |
