Slope Land Sloping cropland generally refers to cropland with a slope greater than 6° Sloping cropland generally refers to cropland with a slope greater than 6°. This type of cropland is a usually dry land with poor ground leveling, prominent water and fertilizer runoff, and low crop yield. Soil erosion refers to the process of soil or its parent material being stripped, destroyed, separated, transported, and deposited under the action of external forces such as water, wind, freezing and thawing, and gravity. According to different types of external forces, soil erosion is mainly divided into hydraulic erosion, wind erosion, gravity erosion, and freeze-thaw erosion. “Soil erosion is mainly divided into hydraulic erosion, wind erosion, gravity erosion, and freeze-thaw erosion.” Soil erosion on sloping land in China is mainly prominent in the loess soil on the Loess Plateau, the red loam soil in the upper Yangtze River hills, the purple soil in the Chuanzhong hills, and the black soil in the Northeast Plain. Among them, Loess Plateau is the most serious and concentrated area of soil erosion on sloping farmland in China. Severe soil erosion has caused thousands of hills and ravines, bare hills and bald mountains, and frequent disasters on
