Progress in Wind Erosion Research

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, store and analyze the wind ero sion information
