Description :
Based on journal publications and a meta-analysis approach, this paper investigates the effects, and their spatiotemporal variations, of different land covers on red soil rehabilitation in China. Results indicate that all the land covers used in red soil rehabilitation had been effective in improving degraded red soils but the degrees of effectiveness varied. Soil organic carbon was the most sensitive of the 3 major soil nutrients considered with regard to land-cover change during ecological rehabilitation. Coniferous and broadleaf mixed forest was detected as the most effective land cover in red soil rehabilitation. Some spatiotemporal trends of land-cover effectiveness on red soil rehabilitation exist in a statistically significant sense. These findings are important for land use and ecological rehabilitation decision-making such as the selection of a soil rehabilitation pathway and the determination of priority areas for ecological rehabilitation.
