| Abstract: | This paper seeks in picture characterization techniques of forecast model for air pollution emergency in urban area, presents the framework of ArcIMS prototype, selection of forecast models, key techniques of its realization. The simulation test suggests that this system is able to veraciously characterize diffusing scope, concentration distribution and other situations of air pollutants in course of emergency. |
