Abstract

In xilingol league area HunShanDaKe sand is one of the main material in our country, at the same time, xilingol league area is the natural barrier of beijing-tianjin-hebei region area in our country, and in the border areas, dust weather of xilingol league area increased significantly in recent years, so the influence of the Mongolian cross-border dust moving path has the vital significance. This study selected in the border area of xilingol league area of Inner Mongolia three meteorological site (that compal lattice, east WuZhu MuQinQi, erlian), the first statistical analysis of spatial and temporal distribution of sand and dust weather in 1980-2015, the second use HSYPLIT model analysis of 2006-2015 after successive dust weather to the trajectory simulation. Results (1) in the border area of xilingol league area three site dust weather are mainly concentrated in 3 to 5 month spring, followed by six to eight months in the summer, three sites in April the most dust weather, respectively, 56%, 49% and 41% of the total. Among them, due to low precipitation and low vegetation coverage, the highest frequency of sandstorms occurs, followed by the renbao lige, east wuzhu mu qin flag. (2) the xilingol league area dust weather 82% comes from Mongolia, outside source area are mainly in southeastern Mongolia desert and gobi desert area, eastern kazakhstan trajectory path is: the north-west Mongolia, southeastern Mongolia, xilingol league area in Inner Mongolia. Among them, 92 percent of the sand and dust weather comes from Mongolia, followed by the east wuzhu mu qin banner and the na ren baolig, 85 percent and 71 percent respectively. The results can provide a certain degree of scientific basis for the ecological construction and environmental protection departments of xilingol league.
