| 摘 要： | 土壤活性有机碳在指示土壤碳库平衡、表征土壤肥力与质量、衡量土壤微生物生长等方面具有重要意义。本文对中亚热带红壤丘陵区松林生态系统93个表层（0～20cm）土壤样品的活性有机碳空间分布特征及其与地形、植被和土壤特性的关系进行了深入分析。结果表明：表层土壤活性有机碳的平均值为1.92g/kg,占土壤有机碳的29.18%,变...

| Abstract: | Labile organic carbon is more sensitive to changes in land management or environment conditions than stable carbon,although it is a smaller fraction of soil organic carbon.It also has a disproportionately large effect on nutrient-supplying capacity and the structural stability of soils.Therefore,the spatial distribution and its influencing factors(topography,vegetation and soil properties) have been analyzed in Pinus elliottii ecosystem of central subtropical region.Results indicated that the mean of soil l... |
