| 摘 要： | 通过定位观测，对不同密度杉木林的树高、胸径与材积生长规律、林分结构、林木分化和材质的差异；并对不同方式间伐后林分的生长变化，以及不同间伐强度对林地土壤肥力、林下植被种类和数量的影响及其经济效果进行了研究。结果表明：林分密度和间伐强度对杉木树高生长无显著影响，而胸径和单株材积则随着林木株数的增加而减小；林下植被种类、数量和土壤肥力均随着间伐强度的加大而有所增加；中度间伐强度的生长、生态和经济等综合效果最佳。

| Abstract: | The study results indicated that the effect of stand densities and thinning intensities on tree heightgrowth was not significant while the dbh and individual volume reduced with the increase of trees;the speciesand quantity of under vegetation and the soil fertility increased with the increase of thinning intensity;and thecomprehensive effects of growth,ecology and economy were optimal for the moderate thinning intensity. |

| Keywords: | Cunninghamia lanceolata density thinning intensity ecological effect |
