【摘要】：空气质量状况的优劣,直接关系到人体健康和经济社会可持续发展。利用2014年黑龙江省4个重点城市的空气质量数据,结合同期常规气象要素资料,分析了黑龙江省AQI指数基本特征及与气象要素的关系。分析结果表明:黑龙江省重点城市年平均AQI指数以哈尔滨最大(轻度污染级别),其次牡丹江、大庆、齐齐哈尔(良级别);单日空气质量指数最高值在大庆(500),其次是哈尔滨(490),牡丹江和齐齐哈尔单日最高值分别为264和251;AQI指数年分布特征是冬季最高,其次秋季,再次春季,夏季最低;首要污染物最多的是PM2.5,其次PM10、NO2和臭氧8 h。AQI指数与平均气温,在年尺度上呈负相关,月和四季呈正相关为主;与降水日呈负相关;与相对湿度是冷月(1—2月)呈正相关,渐暖月(5—6月)呈负相关;与最大风速,采暖季呈明显负相关;与本站气压呈正相关,与日照时数冬季呈负相关关系。
[Abstract]:The quality of air quality is directly related to human health and sustainable economic and social development. Based on the air quality data of four key cities in Heilongjiang Province in 2014, the basic characteristics of AQI index and the relationship between AQI index and meteorological elements are analyzed. The results show that the annual average AQI index of key cities in Heilongjiang Province is the largest in Harbin (light pollution level), followed by Mudanjiang, Daqing, Qiqihar (good grade); the highest daily air quality index in Daqing (500), followed by Harbin (490), Mudanjiang and Qiqihar, respectively 264 and 251 per day AQI annual distribution characteristics are the highest in winter, followed by autumn, again in spring, In summer, PM2.5 was the most important pollutant, then PM10 NO2 and ozone 8h. AQI index were negatively correlated with mean temperature on annual scale, positively correlated with month and four seasons, and negatively correlated with precipitation day. There was a positive correlation with relative humidity (January-February), a negative correlation between warming month (May-June), a negative correlation with maximum wind speed and heating season, a positive correlation with local air pressure, and a negative correlation with sunshine duration in winter.
