中文摘要	在遥感技术与GIS技术的支持下,首先通过遥感影像解译,获取了黄河流域20世纪90年代中期和末期的土地利用与土壤侵蚀数据,建立了反映该流域土地利用与土壤侵蚀的数字环境模型,而后对黄河流域近5年的土地利用与土壤侵蚀的耦合关系进行了研究.结果表明:不同的土地利用方式对土壤侵蚀的发育有着不同的影响,土地利用的变化直接影响着土壤侵蚀强度的变化,而形成土壤侵蚀的一个重要原因是土地利用方式不当.优化土地利用结构,选择合理的土地利用方式,对于高效利用土地资源,控制水土流失,实现区域经济的可持续发展具有重要意义.
英文摘要	Soil erosion is a core field of the global environmental change study. Also the study on the relations be-tween 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 wa-ter 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 in-terpretation 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.
