摘要
Sandy desertification is land degradation characterized by wind erosionmainly resulted from the excessive human activities in arid, semiarid and part of sub-humid regionsin northern China, The research on sandy desertification has experienced more than 5 decades ofarduous course of the struggle along with the establishment and development of China's desertscience. Researches in this field have made a great contribution to the national economicconstruction, and environmental protection. This paper focuses on presenting the major progress andachievements in the sandy desertification research during the last 50 years, including the stages ofstudy on sandy desertification, background environment of sandy desertification and its changes,the conception, causes, process, monitoring and assessment of sandy desertification, the vegetationsuccession, landscape ecology, plant physiology, impacts on ecosystem, high-effective use of waterand land resources and sustainable development in sandy desertified regions, sandy desertificationcontrol models and techniques etc.
