    Abstract:

    In order to understand the soil carbon sequestration potential in subtropical orchards, the changes in soil carbon storage in Yongchun Xian, Fujian, China were studied, and soil carbon sequestration potential was estimated under existing management condition. The results showed that soil organic carbon content in orchard of Yongchun generally rose from 1982 to 2010. The annual variation in soil organic carbon was in the order of south subtropical zone > transition zone > middle subtropical zone. Based on the correlation analysis between average relative annual increment and the initial value of soil organic carbon, the orchard soil organic carbon storage capacities of Yongchun Xian was estimated from 13.74 g kg-1 to 21.05 g kg-1. Under the conditions of land management and climate in 2010, the soil carbon sequestration potential in Yongchun orchards would be 64108.77 t. These could contribute to evaluation the potential of soil carbon sequestration in orchards of China.
