Beijing region is one of the most serious regions which are subjected to the sandstorm disaster deeply.In this paper,we chose Daxing county as study area,in which,an unprecedented heavy sand stormy weather with high frequency took place in the spring dramatically.Therefore,based on the climate data from 1960 to 2004 and TM images data,employing climate statistics methods and RS technology,combining observation on the spots,the authors analyzed frequency of sand stormy weather,climate background,spacial distribution characteristics of desertification patches and activity rule of sandstorm near the earth’s surface.The result showed that,winnowing sand which happened mostly in April and May,is the main disaster weather of Daxing county and even the whole Beijing region,the frequency direction of biggest wind speed were northeast and southwest main wind directions,and desertification patches of study area,which had the trend of reducing gently,distributed principally in watercourse of Yongding river and dunes in the middle of Daxing county.Combining the two results above,we got that threshold wind speed corresponding with underling surface of different land use style is different evidently,and on the basis of that,we brought forward the total project of fathering sandstorm pattern in sandstorm source area,which could offer indication function for preventing and fathering sandstorm in Beijing.
