Abstract
How to assist decision making efficiently using information technologies such as GIS and water environment models has become a hot issue in the field of emergency study. Starting from the actual need of water pollution accident emergency handling, this paper uses scenario analysis, organically couples GIS, water environment accident models and decision making methods, and establishes an intelligent decision making system for emergent water pollution events. Then, with the actual data from Beijiang River cadmium pollution event entered into this system, it analyses and compares the change of pollution situations in different scenarios, and verifies the effects of the study. Finally, it provides a technical summary and prospect.
