空气质量多模式集合预报是研究大气污染演变规律、进行空气质量预报预警,提供大气污染控制管理决策的重要工具.本文介绍了地理信息系统(GIS)与多模式集合预报系统进行集成的设计思路,并对GIS在系统中起到的作用进行了探讨.将GIS技术应用于多模式环境空气质量预测预报系统中,可提供空间数据和相关属性数据的快速存取和管理功能,使环境基础信息与环境管理信息以及模型分析结果以可视化的图形、图像方式呈现给决策管理人员,并能充分发挥GIS的空间分析能力,为辅助决策提供依据.该系统在广州市环境空气质量保障的应用中取得了较好效果.%Air quality multi-model ensemble forecasting is an important tool to study the evolution of air pollution rules, air quality forecasting and warning, and to provide air pollution control management decision-making. In this paper, the design of the integration of geographic information system (GIS) and multi-model ensemble forecasting system was introduced, and the important roles of GIS in this system were discussed. Using GIS technology in multi-model ensemble forecast system, which provides the functions for fast accessing and management of spatial data and attributes data, can make the basic environmental information, environmental management information and modeling results visible to the manager through graphics or images. Meanwhile, the spatial analysis function of GIS is helpful for assistant decision support The GIS based multi-model ensemble forecast system used in Guangzhou City has played an effective role on air quality protection.
