Abstract:

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%,变异系数为46.15%。从不同地貌部位来看,沟道的活性有机碳含量、碳库活度均显著高于坡面。土壤活性有机碳与海拔、乔木地上生物量显著负相关,与灌木地上生物量显著正相关,与土壤有机碳、全氮、全磷、速效氮、有效磷和速效钾呈极显著正相关关系。利用Canoco进行主成分分析表明,第一、二轴可以算是主成分轴,第一轴中主要与土壤有机碳、全氮、速效氮的相关性较强,第二轴中则主要与海拔、pH、全磷、灌木地上生物量相关性较大。土壤碳库活度则与各影响因子的相关性均不显著
