摘要

The TSP mass concentration were successively observed by use of TH1000 air collection instrument in Alashazuoqi, Baotou, Hohhot, Siziwangqi, Jining, Huade, Erlianhaote and Soniteyouqi in Inner Mongolia during a dust storm on April 6th to 7th of 2001.Combined with the routine weather observation data, a comprehensive analysis was conducted. The results show that the temporal and spatial distribution of TSP was apparently various in the process of dust storm. The minimum TSP is 1.896 mg.m-3, the maximum is 52.153 mg.m-3 and the average is 13.399 mg.m-3. The sandstorms in west Inner Mongolia are long distance transported from dust resource in remote Mongolia, while sand storms in central Inner Mongolia depend on local dust rising. The most significant dust source in this case was the desert grass land in central Inner Mongolia, partly derived from the degeneration of grassland in west central Inner Mongolia. Comparing with the maximal TSP mass concentration coming from the anthropogenic source which occurred at the city(Hohhot) in winter, the TSP mass concentration in this case was 10 52 times of that, the pollution from the sand dust storm is much more serious.
