摘　　要：间伐是将成龄人工纯林改造为风景林的抚育手段之一。2007～2008年对南京溧水县无想寺森林公园马尾松林样地进行了弱度、中度、重度强度间伐试验前后的群落学调查结果表明：间伐2年后的马尾松林分平均胸径、树高、冠幅明显大于间伐前，且与问伐强度呈正比关系；群落结构尚无明显改变，植物种数增多，群落开始向针阔混交林演替。该研究为马尾松纯林改造成风景林提供了一定科学的理论依据。Thinning is one of fostering measures to reconstruct the mature artificial plantation. The paper surveys the Pinus massoniana plantation in the perspective of community structure before and after light thinning, moderate thinning and heavy thinning in 2007 and 2008. The results show that the DBH, height, crown length after thinning are significantly higher than that of the control group, and vary in direct ratio according to the thinning intensity; the community structure has no distinct change for the time being; the species number increases; and the plantation is in the succession to the coniferous and broad-leaved forest. The research can provide scientific and theoretical evidence for the reconstruction of Pinus massoniana community from artificial plantation into scenic forest.
