Management information system(MIS),Geographic Information system(GIS),the basic database's analysis of information and the digital technology are providing advanced technical means for developing the emergent decision-making supporting system for the urban's major accident.In the emergent dealing with the urban's sudden and catastrophic accident,making full use of advanced information management tools and building intelligent emergent decision-making supporting system for safety production accident what play important roles in improving the fast,accurate,scientific of the accidents police handling,decision-making commend,emergent energy and resources' management;Enhancing the effectiveness and initiative of the emergent rescuing work;minimizing the losses caused by the accidentThis article starts from the study of the emergent accident at home and abroad,introduces the basic theory and method of the emergent rescuing system,and discusses the emergent rescuing basic principles,tasks and forms with the example of the toxic substances' leakage;and the gives a careful introduction for the model of spatial analysis' application in this paper;describes this system's major function and database's design;finally carefully describes the system's modular design and procedures in the detailed design of the system,including the implementation of the various functions.The innovation lies in this that it not only finishes the analysis of various maps,but also brings the model of spatial analysis into the emergent rescuing area to achieve various accidents' dynamic simulation.According to the different weather conditions,it can simulate different graphics as the changing of time,and display different areas such as deaths,injuries and minor injuries colorfully.Within GIS powerful functions,such as spatial data processing,analysis,display and expression, this paper is to develop the emergent decision-making supporting system for safety production accident.When accident occurs,it can fast gather relative emergent information and carry it to commanding center,quickly simulate disaster scene, predict the developing trends of disaster,generate decision-making programmed with all kinds of elements,dispatch and utilize emergent resources effectively and scientifically,provide scientific basis for the rapid evacuation of persons and emergent rescuing.
