摘要：
Soil total organic carbon (TOC), readily oxidizable C (ROC), and microbial biomass C (MBC) were determined at the different ages of tea in Three Gorges Reservoir area, China. The results showed that soil TOC and ROC in the 0-20cm decreased gradually with age of tea garden, whereas MBC had no significant difference among sites. OC, ROC, and MBC decreased readily with depth. Soil total organic C only showed a significantly positive relationship with readily oxidizable C. The age of tea showed a significantly negative relationship with TOC and ROC.
