In Hubei province,the soil eroded to inner-city is coupling with formidable soil erosion to backg round in the spatial phase, and they form overlying effect together.Integral structure of soil erosion landscape ecosystem is unbalanced in spatial owing to the differences of the climate, geology, geomorphy in Hubei province.In microscale, the Yangtze river and Jianghan plain are the center of sediment and transporting sand, the currents of soil are assemble successively from north, south to the center section, and from west to east walking through center axes.The spatial structure pattern is unsymmet rical block-ring model.The soil erosion to inner-city is come into being of both social and natural factor.
