淄博市空气污染物变化及其与气象条件的关系

近年来淄博市由于加强了对二氧化硫和粉尘等污染物排放企业脱硫除尘的监管,可吸入颗粒物和二氧化硫浓度呈现逐年下降趋势,而燃煤量和机动车保有量的逐年增加使氮氧化物浓度呈现波动式上升趋势;四季分明的气候条件使淄博市的空气污染程度在一、四季度高于二、三季度;同时污染物浓度和风速、湿度呈负相关,和温度、气压呈正相关。

Zibo Air Pollutants Change and the Relationship with Meteorological Conditions

In recent years,due to the measures on strengthening the supervision of desulfurizing and dedusting in SO2 and dust emission enterprises,the concentration of PM10 and SO2 in Zibo city was decreased year by year,but the increase of coal-burning and motor vehicle quantities year by year caused the rolling increase of nitrogen oxides concentration.The climate of four distinct seasons made Zibo city air pollution in the first and fourth quarters was more serious than that in the second and third quarters,and pollutant concentration was negatively correlated with wind speed and humidity,but was positively correlated with temperature and pressure.
