Large rills with catchment areas pose serious soil erosion problems to South China, after deforestation has exposed the deeply weathered granitic slopes to the impacts of tropical rainstorms. The purpose of this study is to determine
the effectiveness of vegetation in controlling the erosion of large rills in South China.
Rainfall provides the primary mechanism for soil erosion in South China. This paper examines the seasonal regime and the spatial pattern of rainfall in the Province of Guangdong. At the regional level, trend surface analysis suggests highest
