| 摘 要： | 利用CAMx模式模拟了2014年春季(3~5月)山东省ρ(PM2.5)浓度空间分布、输送、沉降特征并建立了各市PM2.5跨界输送矩阵.结果表明,山东省ρ(PM2.5)分布呈现明显的空间差异特征,鲁西地区浓度较高,半岛地区浓度较低;垂直方向上ρ(PM2.5)主要集中在2 000 m以下.全省ρ(PM2.5)水平输送通量平均达110μg·(m2·s)-1,全省总沉降量为23.05×104t.全省近地面ρ(PM2.5)外来输送贡献率为21.08%±3.83%,各市外来输送贡献率平均为40.45%±5.96%;随着高度的升高,京津冀、背景及边界等条件对山东省ρ(PM2.5)的贡献率明显上升,分别上升了7.56%、6.18%. |
