中文摘要: 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 .85 4和0 .880。
Abstract:The CAPPS(City Air Pollution Prediction System) was used to simulate the air pollutant index of the primary air pollutants(SO2 NOx TSP) in Shijiazhuang City . The results show that the modification of time coefficient of pollutant emission ( Ti) and the experiential coefficient (Ki) 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 SO2 , NOx and TSP were raised to 0.951 , 0.854 and 0.880 respectively after modifications by TiKi and F.
