| 中文摘要: |
| 对马尾松肉桂人工复层林和马尾松单层林林地土壤理化性质进行测定分析，探讨复层林林地的立地效应。结果表明：马尾松肉桂人工复层林的土壤容重比马尾松单层林低，而土壤总孔隙度、毛管孔隙度、非毛管孔隙度和持水量却高于单层林；复层
林的土壤有机质、全N、全P、全K、水解N、速效P、速效K、交换性Ca2+、交换性Mg2+等均比单层林高。显然，营造马尾松肉桂人工复层林能有效地改善土壤结构，提高土壤肥力，对马尾松人工林地力维护具有重要作用。 |
| 英文摘要: |
| The physicochemical property of soil in the plantation of multi-layer forest for Masson pine(Pinus massoniana) and Cassia bark (Cinnamomum cassia) and single-layer forest for Masson pine were determined and analyzed, and the site effect of multi-layer forest was discussed. The result showed that the soil bulk density in multi-layer Masson pine plantation forests was lower than that of singlelayer forest, but the soil total porosity, capillary porosity, non-capillary porosity and water retention capacity were all higher than those of single-layer forest. The soil organic matter, total N, total P, total K, hydrolysis N, available K, exchange able Ca2+, exchangeable Mg2+ of multi-layers forest were more than that of single-layer forest. Obviously, establishing the plantation of multi-layer forest for Masson pine and Cassia bark can effectively improve soil structure, improve soil fertility, and play an important role in the maintenance of Masson pine plantation. |
