| 摘 要： | 在全国杉木中心产区选择不同栽植代数（１、２、３代）、不同发育阶段（５、１０、１５、２０ａ）及不同立地（１４、１６、１８地位指数）的杉木人工林，进行不同栽植代数杉木人工林土壤肥力的比较研究。结果表明：连栽导致了杉木林地土壤肥力的明显下降，随栽植物代数增加，不同发育阶段杉木林林地水稳性团聚体、非毛管孔隙、田间持水量，毛管持水量、最大持水量及土壤各项养分含量均呈下降趋势，而土壤结构体破坏率和容重却呈增加趋势，林地肥力朝不利方向发展。 |
| 关 键 词： | 杉木 栽植代数 土壤肥力 地力衰退 |

| Abstract: | The soil fertilities of Chinese fir ( Cunninghamia lanceolata ) plantations with different generations are studied through investigating the plantations with different generations,ages and site conditions. The results showed that successive planting results in significant soil fertilities decline of different aged plantation. As planting generation increases,soil aggregate,non capillary pore,capillary pore,moisture capacity,maximum moisture capacity and nutrients of different aged plantations decrease,whereas the rate of structure fragmentation and volume of soil increase. The soil fertilities of Chinese fir plantations become degraded after successive planting. |
| Keywords: | Cunninghamia lanceolata planting generation soil fertility soil fertility degradation8 |
