摘要
根据呼和浩特市2000年6月至2011年3月的空气污染指数和同期的气象数据,分别对空气污染指数的年均值和月均值及其变化规律、空气质量级别及首要污染物等进行了统计分析,并分析探讨空气污染指数和气象要素之间的相关关系。结果表明:呼和浩特市空气质量正逐步变优,优良率已达95.6%;空气污染指数与气压和最大风速呈正相关关系,并与气温和降水量呈负相关关系。
According to the air pollution index and meteorological data on Hohhot from June 2000to March 2011,respectively,the annual average and monthly mean air pollution index and its variation,air quality levels and the primary pollutants were statistically analyzed,and analysis of air pollution index and the correlation between meteorological factors.The results showed that:Hohhot air quality is gradually changing priorities,excellent rate has reached 95.6%;air pollution index with the maximum wind speed and air pressure was positively correlated.It was negatively correlated with temperature and precipitation.
