摘　　要： 对11年生飞播马尾松林进行综合抚育间伐试验的结果表明，不同的间伐强度和次数均产生不同的效果。胸径生长以间伐强度大和2次间伐为好；树干形质以间伐强度小为好；间伐对树高、冠幅、林木分化等均有影响。 The authour carried out an experiment on aerial sowing Pinus massoiana Lamb. stand at the age of 11 year - old by synthetic thinning. The conculusions showed that there were differ-ent effects for different thinning intensity and thinning, it is better to thin the forest stand two times or by strong intensity for breast height diameter growing, and it is good to thin the forest stand by hight intensity for form factor of trees. There are some effects of thinning on tree height and tree crown diameter and tree distribution.
