中文摘要	北京地区是深受风沙灾害严重威胁的地区之一.选择北京市重点风沙源区一大兴区永定河地区为研究对象,以1960-2004年地面气象记录和2005年TM影像为主要数据源,运用气候统计学方法,在遥感技术的支持下,结合实地观测,深入分析风沙源区沙尘天气发生的频次、气候背景,沙化斑块的空间分布特征以及地表风沙活动机制.研究表明:扬沙是威胁大兴乃至整个北京地区的主要灾害性天气,主要发生在4-5月,最大风速频率方向主要为NE和SW两个主风向;研究区沙化斑块主要分布在永定河河道和大兴区中部的沙垄地区,并有逐渐减小的趋势;结合以上结论,得出不同土地利用类型下垫面对应的起沙风速显著不同,在此基础上,提出北京市风沙源区治沙格局的总体思路,为北京地区风沙防治提供一定的指导.
英文摘要	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.
