摘要
根据包头市2015—2016年PM_(2.5)监测数据及气象数据,分析了包头市PM_(2.5)时空分布特征及PM_(2.5)与气象因子之间的关系。结果表明:包头市PM_(2.5)浓度在12月达到最大,日变化曲线为双峰型;在空间上PM_(2.5)浓度由西南向东北方向递减,且浓度梯度变化明显;气温、相对湿度、降雨量、风速等气象因子对PM_(2.5)浓度有显著影响。
By using the monitoring data of PM2.5and meteorological date of Baotou from 2015 to 2016, the temporal and spatial distribution of PM2.5 and the relationship with meteorological factors in Baotou were analyzed. The results showed that the PM2.5 concentration in Baotou reached the maximum in December, and the trend of its diurnal variation was bimodal. In space, the PM2.5 concentration decreased from southwest to northeast. The meteorological factors, such as temperature, relative humidity, rainfall, wind, had significant influence on PM2.5 concentration.
