摘　　要：利用气象和环保资料详细分析了武威市空气质量的特点,针对不同季节、不同时次分别建立了沙尘暴短时、短期预报模式及空气质量统计预报、潜势预报模式,经检验效果良好。应用Fortran和VB语言设计编程,建立了武威市空气质量预报系统,该系统包括沙尘暴预报预警服务系统、空气质量统计预报系统和空气质量潜势预报系统,直接和MICAPS系统接口,具有资料处理、动力统计预报、潜势预报等模式计算及资料采集、处理、模式运行、预报显示、产品分发、资料查询、预报评分等多种功能,在业务应用中效果良好。The characteristics of urban air quality are analyzed in detail by means of the meteorological and environmental data. The results indicate that the high frequency of the sandy weather is the prime reason that made air quality worse. The short-time and short-term forecast equations of sandstorms and the statistical and latent equations of air quality are built up for different seasons and different periods of time, respectively. It is proved by tests that the the systen performs well. The Fortran and VB languages are used in the design of the programs and the establishment of the air quality forecast system for Wuwei. This system includes three parts： the sandstorm forecast, early-warning and service system; the air quality statistical forecast system; and the air quality potential forecast system. The interface designed by the VB language is directly connected with the MICAPS system, and there are multiple functions such as data processing, dynamic statistical forecasting, potential forecasting model, as well as data collecting and processing, model running, forecast display, results distributing, date inquiring, prediction scoring, etc. The system is simple, user-friendly, fast, and easy to operate and has abundant functions.
