德州市区空气质量与气象条件的关系
|
摘要
选取德州市区2008年7月~2014年6月逐日的空气质量监测数据和同期的逐日气象观测资料,分析近40年来气候变化特征和近6年德州市区空气质量变化特征,研究了气象要素与空气质量指数之间的关系。结果表明,德州市区空气质量与气象因子关系密切,最为密切的主要因子有相对湿度、能见度、雾、霾。通过线性逐步回归分析建立AQI预报模型,得出德州市区影响AQI的气象影响因子在4个季节中均有霾入选,秋季除了霾之外还有平均能见度、大雾,而全年、夏季、冬季除了平均能见度、大雾之外均有轻雾、霾、平均相对湿度。
Selecting daily air quality monitoring data and daily meteorological data from July 2008 to June 2014 in Dezhou City,characteristics of climate change in recent 40 years and air quality change features in latest 6 years were analyzed,the relationship between meteorological elements and air quality index was studied. The results showed that air quality in Dezhou City was closely related to meteorological factors,the most important factors included relative humidity,visibility,fog,haze. AQI forecast model was established by linear stepwise regression analysis,it was concluded that haze was the factor influencing AQI in all seasons. In addtion to haze,factors influencing AQI in autumn also included the average visibility and dense fog; while that in summer,winter and whole year,light fog,haze,average relative humidity were involved besides the average visibility and dense fog.
