| 摘要: |
| 介绍了广东省结合森林资源连续清查开展林地土壤监测的1988年、2002年及2007年的调查结果的总体情况。2007年监测结果表明A层（腐殖质层）、B层（心土层）理化性质存在显著差异，A层的多数主要肥力因子明显优于B层，但A层的酸度比B层大。3次监测结果表明，主要肥力因子中，土壤孔隙结构、容重、有机质和N素有所改善，但土壤酸度持续增强，土壤P、K素仍没有得到明显的改善。 |

| Abstract: |
| This paper introduces the soil monitoring system which applied to the Continuous Forest Inventory (CFI) and the search results in 1988，2002 and 2007 in Guangdong Province. The monitoring results in 2007 indicated that remarkable differences of physical and chemical properties existd in layer A soil and layer B soil, the dominant soil fertility factors in layer A were obvious better than that in layer B, conversed in soil acidity. The three times monitoring results indicate that soil porosity and structure, soil bulk density, soil organic matter and soil N are improved, but soil acidity increase sustainedly, no evident improvement in soil P and K are found.
