VEGETATION EFFECTS ON SOIL AND WATER LOSSES ON WEATHERED GRANITIC HILLSLOPES, SOUTH CHINA

Deforestation of weathered granitic hillslopes of South China has led to widespread erosion. Using small experimental plots under different vegetation cover, this study examines the effects of land use on soil and water losses. Overland flow increases as the cover conditions change from forest to fern, to tilled soil and, eventually, to bare ground. This is related to the amount of interception and infiltration, both of which decrease as the …
