| 摘 要： | 本研究对黄土丘陵区20，25，40和50年人工刺槐林土壤团聚体稳定性与植物群落特征相关性进行了分析，结果表明，刺槐群落的总物种数和细根密度对土壤团聚体水稳定性有显著影响（R2≥0.96），物种多样性和禾本科物种数对土壤团聚体机械稳定性作用明显（R2≥0.97），刺槐群落特征影响土壤团聚体稳定性。 |
| 关 键 词： | 人工刺槐林 植物群落特征 土壤团聚体稳定性 相关性分析 |

| Abstract: | The correlation analysis of soil aggregate stability and plant community characteristics were studied under different-aged Robinia pseudoacacia plantations (20,25,40 and 50 years old) in Loess Hilly Region of China.The results showed that:the Shimpson index and Gramineae species had significant effect on the soil mechanical-stable aggregates;species number and fine root density significantly affected the soil water-stable aggregates.In summary,Robinia pseudoacacia plant community characteristics affected the stability of soil aggregates. |
| Keywords: | Robinia pseudoacacia plantation Plant community characteristics Soil aggregate stability Correlation analysis |
