GIS-based Visual Simulation on Two-dimensional Diffusion of River Pollution

摘要

The visual simulation on diffusion of water pollution is a key technology to reveal the diffusing transport of pollutants in the water. Based on two-dimensional diffusing model of water quality, this paper mainly does research on the methods and procedures to visualization of the diffusion of pollution combining means of visual simulation on point pollution with the GIS technology. And the diffusion of point source pollution in a certain river is taken as an example in the paper so as to verify the effectiveness of the given method.
