粉尘释放和沉积机制的研究进展

he dust aerosol emission from surface by wind erosion. In its transport and deposition process, the dust aerosol give direct and indirect environmental effects. It promote the study of the mechanism of dust emission and deposition. With soil erosion research and development, the mechanism of the dust emission has deeper. The research from the model of the easy experiential equation to clear physical mechanism of the dust emission model with the current dust emission of the micro-process, and widely were used in forecasting of dust at large-scale study. Dust deposition study was concentrated in clouds of dry deposition and removal process, but not recognize the process of in the cloud. In this paper, author gave a brief review of the mechanism of dust emission and deposition and the development of history, systematically reviewed the status of research and put forward the dust emission and deposition in the simulation of the existing problems and future trends.
