摘要
选用郑州市城郊7个代表站2006年可吸入颗粒物PM10、二氧化硫和二氧化氮等主要污染物逐日浓度监测资料,分析了郑州市这3种主要空气污染物的时空分布特征及其与气象条件的相关性,并利用2001-2006年均浓度资料分析了主要污染物浓度的变化趋势。
Using the day-to-day observation data of seven stations in the outskirts of Zhengzhou in 2006, the spatial and temporal distribution characteristics of PM10, SO2 and NO2 are analyzed, and the correlation between main pollutants and meteorological condition is also summarized. The change tendency of main pollutant concentration is studied by analyzing the mean annual concentration data from 2001 to 2006.
