This thesis made a preliminary attempt to design the patterns of the regional soil erosion,based on its former research accomplishments of the regional and sloping soil erosion as well as the analysis of its process.The main contents were as follows:1).To divide the regional soil erosion into two sub-processes of water and sand,according to the description of the process of sloping soil erosion;2).To build up the relevant mathematical patterns,taking the process of the regional soil erosion into considerati...
