This paper was mainly to solve how to accurately and visually simulate the toxic gas diffusion process. ArcGIS Engine drawing methods and key technologies were used, and gas leak emergencies based on Gaussian plume model was selected as a typical scene of emergency evacuation simulation system, dynamic simulation of gas diffusion based on t was implemented, and three key parameters, leakage source strength Q, wind speed V, surface roughness Z0, that affect results of gas diffusion were briefly analyzed and researched. The results show that simulation system can simulate dynamic diffusion processes after leak of toxic gas, and can quickly and accurately draw and calculate regional distribution of equal concentration about three areas at any time after leakage of toxic gas. The results of simulation can have a good assistant decision function on prediction and assessment of toxic gas leakage accident scene.
