中文摘要	利用沙尘暴监测网数据、常规气象资料以及MICAPS系统环流形势资料,对和田市2004年春季沙尘天气产生的污染进行了详细的对比分析.研究结果表明:和田市春季污染相当严重,主要以沙尘污染为主.整个春季79%时间API(环境污染指数)指数均达到500,且45%时间可吸入颗粒物PM10在TSP中的浓度比例达50%.不同天气系统对和田市空气的污染贡献不同.从东路影响和田市的天气系统、高压底部型地面系统和浮尘天气所造成空气污染相当严重.其余天气系统和天气现象所产生的污染较小.
英文摘要	Hotan Prefecture is located in the south of Xinjiang Uygur Autonomous Region, and its area is 2.48x10 km2 and occupies 14.8% ofthe total land area ofthe autonomous region. In the prefecture it belongs to the arid desert climate, the prefecture is rich in sunshine, the annual precipitation is 33.4 mm only but the annual evaporation is as high as 2602 mm, the topsoil is loose, the vegetation coverage and the relative humidity are low, and strong winds occur frequently. All these provide the conditions for the occurrence of dust weathers, and the annual days of occurring dust storms, blowing sands and floating dusts are 32.9, 53,1 and 202.4 days respectively. Therefore, people’s health is seriously threatened. In this paper, the air pollution caused by dust weathers in spring in Hotan City is analyzed using the observed data of dust storms and MICAPS as well as meteorological data. The results show that air pollution in Hotan City in spring is extremely serious and mainly caused by dust. The air pollution index (API) in the city in whole spring is as high as 500, and the concentration proportion of PM]0 in TSP is as high as 45% during 50% ofthe time in spring. The contribution of the different weather systems to air pollution is different. Air pollution caused by the east-route weather system, high-bottom-ground surface weather system and floating dust weather system is extremely serious, and that caused by other weather systems and weathers is relatively slight.
