Based on the unified framework of “digital government”, an air quality comprehensive analysis system was designed and established based on big data intelligent technology. Integrating the functions of air quality big data integration, data audit, monitoring and alarm, comprehensive analysis, compliance management and source identification, a mathematical model for urban air quality comprehensive supervision was established to realize rapid analysis and visualization of air quality big data, air quality prediction and evaluation, comprehensively improve the comprehensive monitoring and analysis ability of urban ambient air quality, timely and rapidly respond to abnormal conditions of urban ambient air quality, and provide technical support for the accurate control of ambient air and ensure the accuracy of data from air monitoring stations. |
