摘　　要：利用城市大气污染数值预报系统CAPPS的第三版(CAPPS3),经过安装、调试和本地化、自动化处理,建立起适合于辽宁的区域空气质量数值预报系统,用于预报辽宁的城市污染指数和等级以及各污染物的日均浓度分布。通过模式预报结果与监测资料的对比,发现辽宁14个主要城市SO2、NO2预报准确率的总体水平明显高于PM10。区域污染物浓度分布位置和大小的预报结果与实际情况相符,污染物小时浓度的演变也与实际风场的变化趋势保持一致,表明CAPPS3模式系统能够及时准确地预报出区域污染的形成和发展过程。After processings of installation, adjustment, localization and automation, the 3rd v ersion of city air pollution prediction system （CAPPS3） is used to establis h the regional air quality numerical forecast system suited to Liaoning to forca st city pollution index, pollution level and the daily mean concentration distri bution of pollutants in Liaoning. Comparisons between forecast results and obser vation data show that the forecast accuracy of SO2 and NO2 in the 14 main cities of Liaoning are higher than th at of PM10. The location and value of regional pollutant concentration ar e realistic and the change of hourly pollutant concentration is also consistent with the ch ange of real wind, indicating that the CAPPS3 is able to exactly forecast the genesis and develo pment of regional pollution in time.
