The Causes and Prediction and Forecasting of Erosion in Bedrock Areas of the Yellow River Basin: A Social Welfare Project of the Ministry of Science and Technology (MOST) for the Scientific Research Institutes (SRIs), with the leaders of researcher Shi Jianshang and researcher Ye Hao. The main completion personnel include Cheng Yanpei, Hou Hongbing, Shi Yingchun, Guo Jiao, Wu Lijie and Wang Qiangheng. The main research content is the erosion mechanism of arsenic sandstone. After three years of research, the project shows that the pink arsenic sandstone has the strongest erosion resistance, and the gray-purple-red interlayered arsenic sandstone has the weakest erosion resistance; using "3S" technology, the erosion of the arsenic sandstone ditch edge line was predicted. The prediction results show that the erosion of arsenic sandstone is not only related to the stratigraphic combination of rocks, but also related to the thickness and loose degree of surface cover; it is proposed that, on the basis of the existing soil and water conservation project, different types of surface cover sands should be targeted to focus on the treatment, in order to alleviate the intensity of the region's rock and soil erosion.
