A STUDY OF GIS-SD BASED TEMPORAL-SPATIAL MODELING OF WATER QUALITY IN WATER POLLUTION ACCIDENTS

In this paper, the one-dimension river quality system dynamics model was applied to the water quality simulation, and the conceptual GIS-SD frame was constructed. Based on the component GIS and system dynamics model, the experimental system of water quality simulation in water pollution accident was developed. The Songhua River water pollution accident which happened on November, 2005 was used as an example to show how the temporal-spatial change of nitrobenzene concentration can be dynamically simulated. The results showed that the simulation of temporal-spatial distribution of the pollutant in water pollution accident, the model regulation, and the scenario analysis can provide the decision-makers with scientific evidence to optimize the related emergency response measures. * Bo Zhang, 861084640954, zhangbo@zhb.gov.cn.
