Abstract

In this study, slope cropland and 5 typical revegetation types mainly in the Zhifanggou catchment area, in the central region of the hilly Loess Plateau, were selected, and then classified into 36 groups according to different revegetation years and landforms to investigate temporal and spatial variations of soil organic carbon (SOC) and the impacts of relevant factors following revegetation. The results showed that the SOC concentration in the top soil horizon (0-5 cm) increased most significantly with revegetation and that increases in SOC slowed with increasing soil depth. It is also highlighted that : 1) slope aspect had more influence on SOC sequestration rather than slope gradient; 2) revegetation chronosequence and types dominated SOC sequestration variation; 3) impacts of slope aspect, vegetation conditions and litter need to be considered
