Soil erosion developed with the vertical belts in the gentle hilly black soil regions in Northeast China

There are unique soil erosion and sediment yield characteristics in the gentle hilly black soil regions of the Northeast China for its unique physiogeographic condition and humanistic community. According to the soil erosion investigation, which was conducted by using remote sensing, the field sampling and the practical investigations, the universal laws of soil erosion developed with the macroscopic and microscopic vertical belts have been summarized for the Gentle Hilly Black Soil Regions of China. The basic models of sheet erosion and gully erosion taking place on slope have been generalized for this region. This research results are helpful to improve the understanding of the soil erosion process, and the sediment source and deposition place can be defined too. Accordingly, the research results, furthermore, provide the theoretical basis for the appropriate collocation of soil and water conservation measures.
