Abstract

In this study, tree survival and growth, vegetation recovery and differences in soil erosion between afforestation with FSP slopes (AFS) and natural restoration slopes (NRS) were analyzed, and the suitability of afforestation with FSPs in the steppe zone of the Loess hilly–gully region was assessed by field survey. the study sites were 2 watersheds located in the Yan River Basin of Ansai County, North Shaanxi Province. All 3 tree species afforested using FSPs exhibited a "small-aged tree" trend due to the poor growth conditions. The coverage of herb and litter in the AFS were lower. The rill erosion caused by FSPs was higher than the sediment deposition in FSPs. Therefore, the AA. conclude that afforestation with FSPs is not effective in controlling soil erosion and improving vegetation recovery. Large-scale afforestation with FSPs is unsuitable in the steppe zone on the hilly-gully Loess Plateau
