Soil erosion is a core field of the global environmental change study. Also the study on the relations between land use change and soil erosion is significantly important for better understanding environmental management for sustainable development. In Yellow River Basin the soil erosion is known for its severity in the world, especially in Loess Plateau, the ecological environment problem such as grassland degeneration, sandy desertification and water erosion have seriously affected on the regional sustainable development. In order to study the relations between land use and soil erosion in Yellow River Basin, the technologies of remote sensing and geographical information system were used. At first, the data of land use and soil erosion were gotten from Landsat TM Images by expert's interpretation for five years, then the digital environmental model were built and the relationship between land use and soil erosion were analyzed for recent five years. The result shows that the soil erosion is affected by the different land use ways, and the irrational land use will accelerate soil erosion. So the rational land use ways and optimized land use structure are significantly important for regional sustainable development.
