摘要


根据时间变化特征,空间分布,气象效应分析,对湖北省武汉市2017-2019年期间的颗粒物浓度数据进行了综合分析。2017年(2018年,2019年),武汉的PM₂.₅年均浓度为52.2μg/m³(46.5μg/m³,44.8μg/m³),PM₁₀的年均浓度为89.3μg/m³(77.7μg/m³,72.5μg/m³),超过国家环境空气质量日均浓度二级标准的天数分别为PM₂.₅:70天(49天,38天),PM₁₀:31天(21天,9天),大气环境质量在逐步改善。武汉市各监测点污染浓度之间的空间差异性很小,总体而言,武汉市的东北部地区颗粒物浓度要高于西南部地区,蔡甸区和汉南区的空气质量相对较好。颗粒物浓度与温度,湿度,风速均呈现出负相关关系。这些结果为这些武汉市的大气污染预测和控制提供了科学依据。
