Open publisher page 0 citations

Abstract

Based on the distribution of hydrological stations and it's observation series of sediment information and the different soil erosion type areas on the loess Plateau, the study area was divided into 292 soil erosion units. The time and spatial variation of sediment yield intensities on the loess plateau were analyzed. The results are showed that sediment intensities have changed evidently because of rainfall factor and the effects of soil and water conservation, and the sediment area with erosion modulus 10,000t/(km 2 a) reduced rapidly. And taking
