中文摘要	分析并找出影响北京沙尘暴天气的源地，该源地主要位于北京北部的浑善达克沙地的西北部边缘，内蒙古中西部，河套以西地区的沙漠，荒漠化地区以及干旱，半干旱地区广大的农业开垦区，指出影响北京的沙尘传输路径有3条，即西路，北路和西北路，对源地的气候特征做进一步分析表明，源地的气候特征为温暖干旱，降水不足，这些因素加速了沙尘天气的发生，同时将源地春季降水和北京沙尘天气相比较。发现北路和西北路源地春季降水和北京沙尘暴天气有较好的负相关，西路源地春季降水和北京浮尘天气有较好的负相关。
英文摘要	The sources affecting Bejing’s dust storm weather are analyzed and found out,which are mainly located in desert,desertification re-gions and vast agriculture reclamation areas in arid and semi-arid areas that are in the west fringe of the Hunshandake Sand in morth Beijing, in the center and west region of Inner Mongolia,and in the west He-Tao area.There are three dust transport paths that influence Beijing,i.e. west route,north route and northwest route.The climate characters are further analyzed and shown to be warm,drought and lacking precipitati-on, which accelerates formation of dust weather.In addition,dust sources spring precipitation and Beijing’s dust storm frequency are compared. There is a distinct negative correlation between Beijing’s dust storms frequency and spring precipitation at northwest route and north route dust sources,while there is a distinct negative correlation between Beijing’ s floating dust frequency and spring precipitation at west route dust sources.
