Simulation and Study of Poisonous Gas Diffusion Based on Arc Engine Techniques about the City after the Earthquake

摘要

This paper presents a dynamic simulation, using Gauss plume model and through component-based software development under ArcGIS Engine, of poisonous gas diffusion after an earthquake. Given certain meteorological condition, topography, and time interval, the simulation provides a satisfactory prediction about the locations and damage ranges of the diffusion process, and, therefore, helps the rescuers make emergency plans which could reduce disaster losses.
