According to the problem of insufficient performance ability for water pollution transport simulation, by adopting to the digital earth technology and complexity theory, the data resources of water pollution event was integrated. The trunk stream of watercourse was decomposed into multi-scale resolution. A water quality complex agent was established with characteristics and behavior patterns. And the efficiency of the migration of calculus was improved by introducing of high-performance computer technology. Then a water pollution transport simulation framework was constructed based-on the digital earth technology which merging together the water quality model and having high expressive force. Results show that this framework has enhanced the ability of spatial representation of pollutant transport process, and provided an integrated platform for pollutant transport simulation and scenario analysis.
