摘要
利用巴彦浩特2010年1月至2011年2月PM10、SO2、NO2的逐日监测数据和同一时期气象观测资料,分析巴彦浩特空气污染物特征及PM10浓度与沙尘天气之间的关系。分析结果表明:2010年春、夏、秋三季巴彦浩特的主要污染物是PM10,冬季主要污染物是SO2;沙尘天气是造成巴彦浩特PM10浓度变化的最重要因素;影响巴彦浩特空气质量的沙尘主要来源于其西北方向和西北偏北方向。建议有关部门在巴彦浩特西北地区搞好生态保护与建设,以减轻沙尘天气对巴彦浩特地区空气质量的影响。
By using daily monitoring data of PM10,SO2,NO2 and the same period of meteorological observation data in Alxa, analysze air pollutant characteristics and the relationship between PM10 concentration and sand dust weather. Analysis results indicate：2010 spring, summer, autumn three season main pollutant in BayanHot is PM10, winter main pollutant is SO2; Sand dust weather is the most primary factors of causing PM10 concentra- tion changes in the BayanHot;BayanHot dust comes mainly from the northwest and north-northwest. Suggest the relevant departments does well ecological protection and construction in northwest area of BayanHot,in order to reduce dust weather influence to air quality in BayanHot area.
