| 摘 要： | 应用CAPPS城市大气污染潜势和污染指数预报系统，对石家庄市主要大气污染物（SO2，NOX，TSP）的污染指数（API）进行模拟分析，结果表明，用CAPPS作城市大气污染预报时，应加入污染物排放的时间系数（Ti)订正和经验系数（Ki)订正，对北方城市而言，还须加入扬尘百分率（F）订正，用加入Ti,Ki和F订正后的CAPPS预报系统，对石家庄市大气污染物（SO2，NOx,TSP)进行模拟，结果SO2，NOx,TSP三种污染物的预报值与其监测值的相关系数分别提高到0．951，0．854和0．880。

| Abstract: | The CAPPS(City Air Pollution Prediction System) was used to simulate the air pollutant index of the primary air pollutants(SO 2 NO x TSP) in Shijiazhuang City . The results show that the modification of time coefficient of pollutant emission ( T i ) and the experiential coefficient ( K i ) should be added when it being used. It also needed to modify with the percent of raising dust ( F ) to the CAPPS in the cities of North China. The correlation coefficients between the predictions and the observations of SO 2 , NO x and TSP were raised to 0 951 , 0 854 and 0 880 respectively after modifications by T i K i and F . |
