Description :
Sand-filled splash cups were used to study the erosivity of rainfall and throughfall in the humid subtropics of southeast China. The results showed that the splash cup measurements yielded precise and reproducible results both under open field conditions and under forest vegetation. The splash cups were exposed to forest stands of different age and to selected species (Schima superba, Castanopsis eyrei) in the Gutianshan National Nature Reserve (GNNR). The results obtained under forest vegetation show that the erosive power of throughfall drops is 2.59 times higher compared to the open field. Moreover, the results show that the erosion potential under forest is related to the forest structure, especially height and canopy cover, and is species-specific.
