Abstract

The features of sediment-producing by erosion of steep slope land in loess hilly regions were analised

The course of sediment-producing by erosion and sediment-producing amount by rainly erosion have been studied by using the simulated experiments of artificial rainfall and the data of natural runoff plots.At the same time

the regressional analysis have been carried out between sediment-producing amount by splash erosion and its influencing factors.The results show that the sediment-producing amount by splash erosion accounts for from 22 per cent to 54 per cent of the toral sediment-producing amount in the simulated experiments.The calculation model for the sediment content course of sediment-producing by rainfall erosion were developed based on the experimental researches and developing model.The test on this model shows that the model has a composition and a better applicative.
