Nowadays, more and more abrupt environmental pollution accidents have occurred in counties of China and seriously influenced the ecological security. It is important to make systematic studies on the occurrence of abrupt environmental pollution accidents in counties. Limited researches have been made on it in China, and it is almost impossible to make early warning and emergency management in time on abrupt environmental pollution accidents in counties. This paper established an efficient emergency management system on abrupt environmental pollution accidents in counties of China based on the technology of Geographic Information System (GIS). The framework, the design of its database and the functions of its modules were discussed and an example was described to show the practical use of the system. This system will support the establishment of emergency response and prevention system on abrupt environmental pollution accidents in counties of China
