Abstract:

The arid and semi-arid areas in China are the important agricultural development regions. There are serious wind-erosion and dust emission in these regions, which threaten the sustainable development of agriculture and the balance of ecosystem. At present, dust emission schemes in weather and climate models only consider wind erosion over desert, and those occurred in farmland are seriously ignored or underestimated. It leads to large uncertainty for estimating dust physical processes and its climate impacts. This review summarizes scientific findings that have been published regarding the characteristics and parameterization of wind erosion in arid and semi-arid areas of China since the 1950s. The research progress and existing problems of wind erosion observation and numerical simulation in arid and semi-arid areas of China are discussed. It is of great significance for preventing and controlling wind-erosion, land desertification and understanding the impact of land use change on air pollution in arid and semi-arid areas of China in future.

Key words: arid and semi-arid area, farmland, soil wind erosion, wind tunnel experiment, parameterization
