| 摘 要： | 基于2015年新疆12个城市的PM_(10)和PM_(2.5)地面监测数据,并结合同期气象观测数据,分析了新疆PM_(10)和PM_(2.5)质量浓度的时空分布特征及其与气象要素的关联性。结果表明:新疆大气颗粒物年均质量浓度呈现南高北低特征,南疆各城市的年均PM_(10)质量浓度为150～262μg/m~3,年均PM_(2.5)质量浓度为50～118μg/m~3。北疆各城市的质量浓度相对较低,年均PM_(10)质量浓度为28～139μg/m~3,年均PM_(2.5)质量浓度为13～74μg/m~3。从时间变化来看,在春季和夏季,新疆以粗颗粒物污染为主,冬季以细颗粒物污染为主。此外,在南疆各城市3月PM_(10)质量浓度突然大幅升高与相对湿度明显下降、风速增大直接相关,沙尘天气是导致该区域春季高PM_(10)质量浓度的重要原因。
