| 摘 要： | 对采暖期与非采暖期PM2.5和PM10的浓度变化特征以及采暖期PM2.5浓度与气象因子的相关性进行分析，结果显示：采暖期PM2.5和PM10的质量浓度显著高于非采暖期，平均是非采暖期的1.85和1.46倍，采暖期PM2.5在PM10中的比重也高于非采暖期。PM2.5浓度同时受几种气象因素的影响，与辐射量、气压和能见度呈负相关,与相对湿度和总云量呈正相关。

| Abstract: | The variation trend of PM2.5 and PM10 concentrations in heating period and non-heating period as well as the correlation of PM2.5 and the synchronous meteorological factors during the heating period were analyzed.The results were as follows: PM2.5 and PM10 concentrations in heating period is markedly higher than in non-heating period,it is 1.85 and 1.46 times higher than in non-heating period in average,the proportion of PM2.5 to PM10 in heating period is higher than in non-heating period.PM2.5 concentratio... |
