    Abstract:

    Pisha sandstone area in the Yellow River Basin is a region with severe ecological degeneration in northern China. The soil erosion control in Pisha sandstone areas has long been one of the difficult problems for many soil and water conservation scholars. The difficulty lies in the alternating occurrence of multiple composite erosive forces such as water, wind, freeze-thaw, and gravity. In addition, the evident space-time separation of erosion and the complex of erosion lithology mechanism and erosion dynamic process in Pisha sandstone areas which has climate characteristics of drought, lack of water and the concentration of heavy rain, and the knowledge limitations of researchers also increase the difficulty. The research and practice progress of the soil erosion characteristics, the effects and benefits of the erosion control measures and the new technologies of controlling soil loss in Pisha sandstone areas were reviewed, and the existing problems were also proposed. The integration of erosion resistance with vegetation restoration, the combination of the Pisa sandstone utilization with the development of eco-derived industries and implementation of the ecological comprehensive treatment will be the main development aspects of soil erosion control technologies for Pisha sandstone areas in the future.
