英文摘要：

The sand-dust storm is a kind of disaster weather with serious harmfulness. It has drawn more and more attention during recent years. The formative causes, sources, moving routines, distribution and evolution rules of sand-dust storm were summarized. The characteristics of atmospheric circulation,physical and chemical characteristics, numerical simulation and forecast methods on sand-dust storm were also discussed. The key scientific tasks of sand-dust storm in China are suggested according to the development stratagem of China ministration （CMA）.
