西安第十四届全国运动会及残特奥会前后PM_(2.5)溯源研究

基于2021年9月~11月西安市环境空气质量监测数据,分析十四运会及残特奥会前中后期西安市区域PM_(2.5)的污染特征,利用HYSPLIT模型、潜在源贡献因子法(PSCF)和权重浓度轨迹法(CWT)确定气团输送路径、潜在源区及其对PM_(2.5)质量浓度的贡献.结果表明:研究期间西安市以东南风为主导,PM_(2.5)浓度在十四运会期间最低,残特奥会结束后最高.PM_(2.5)的气团输送路径以陕南附近的本地输送、偏东和偏南方向的近距离输送以及西北方向的远距离输送为主.PM_(2.5)的潜在源区主要分布在河南湖北、贵州四川重庆、新疆内蒙地区以及陕南各城市及周边省份交界处.

我国十运会女篮决赛阶段防守现状分析与对策研究
