[Effects of land use change on soil readily oxidizable carbon in a coastal area of northern Jiangsu Province, East China].

Soil readily oxidizable carbon (ROC) is a sensitive index to indicate the early changes of soil organic carbon (SOC), and has important value to research the stability and dynamics of SOC pool under the backgrounds of human disturbance and global climate change. To further understand the effects of land use change on soil ROC, an investigation was conducted on the soil ROC content and related factors in four different land use types (grassland, farmland, poplar-agriculture system and pure poplar plantation) in a coastal area of northern Jiangsu Province, East China. The soil ROC content was in the order of grassland < farmland
