Wind erosion is an environment process of soil particle movement forced by wind ,including the sub processes of soil particle entrainment,space transportatio n and deposition Nowadays,scientists and the public pay more attention to the excessive wind erosion because it causes serious environment disaster The mon itoring,evaluation and prediction about the scope,intensity and magnitude of wind erosion are in focus, and they are developed in different spatial / tempora l scales which include profile scale,field (pattern) scale,region scale and an nual,monthly,daily,and hourly scale According to the research aims,means a nd scales,current researches can be cataloged as 4 main aspects: laboratory or field wind tunnel experiments,field investigation and net monitoring system,wi nd erosion evaluation model research,and wind erosion process modeling or quant itative simulation prediction The first topic is essential to deeply understan d the physics of wind erosion,and the second can help transform the research fr om local scale to global scale Thirdly, there are more models to evaluate wind erosion in the source regions than in the transforming paths and the deposition zones In the aspect of simulation and prediction model system of wind erosion ,some models and systems have gained exciting results in some regions by specif ic scale However,more works are needed to generalize them in other regions o r by other different scales In all research aspects, the geographic informatio n techniques, including remote sensing and GIS(Geographic Information System) is and will be the most important tools to acquire.
