Abstract Simulated rain is a valid tool to examine soil erosion on sloping land. 36 simulated rainfall experiments with different rainfall intensities and durations are completed on three different types of land in typical rocky desertification land slope in northern Guangdong Province. Results show that soil erosion amount decreased in fluctuation under same land surface condition during rain process; under typical rainfall intensity, the sediment yield from bare land is more than from grassland and cultivated land. Vegetation cover has important impact on sediment yield, especially under heavy rainfall intensity.Contour ditch farming can reduce sediment yield under small rainfall intensity, but the effect reduces with rising of rainfall intensity.
