| 摘 要： | 干旱半干旱地区是中国的农业后备战略基地，然而近年来该地区农田土壤风蚀现象严重，沙/尘释放量显著增大，威胁农业的可持续发展和生态系统平衡。目前绝大部分的天气和气候模式仅考虑了沙漠地表起沙，忽视退化农田的土壤风蚀起沙，导致起沙通量模拟存在很大的不确定性。对20世纪50年代以来干旱半干旱区农田土壤风蚀起沙特征及参数化做了详细的分析总结，回顾并梳理了干旱半干旱区农田土壤风蚀观测和数值模拟的研究脉络以及存在的问题，为提高农田起沙的模拟精度提供了有效参考，对中国干旱半干旱区农田土壤风蚀防治、土地荒漠化治理以及理解未来土地利用改变对大气污染的影响具有重要意义。

| 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. |
