【 摘 要 】

Soil erosion is a major environmental problem for human survival and sustainable development, which has been seriously threatening human ecological security. The Loess Plateau is one of the most severe areas of soil erosion in the world. Unreasonable land use is an important cause of soil erosion. In recent years, the significant progress has been made on land use and soil erosion. The paper finds: (1) soil erosion models have gradually improved; (2) assessment results of land use and soil erosion which are based on RS and GIS technology have become more accurate and efficient; (3) the research has been gradually increasing at different spatial and temporal scales. However, the current existing models are less versatile and most of them are focus on single-scale research. The achievement of the above results and the continuous research in the future are of great significance for the optimization of land use pattern and the comprehensive management of regional soil erosion in the Loess Plateau.
