Abstract： The present paper is aimed at establishing a safety and emergency information control system through study of the space technology of geographic information system （GIS） and the evolution of dynamic process simulation with the actual accidents based on the research of the emergency process, safety and emergency control practice. As a matter of fact, the so-called safety and emergency control processes usually include classification of blowout accidents in natural gas wells （e. g. hydrogen sulfide （H2S））, the public protection method for such accidents （e. g. H2S）, the early warning forecast of such events （e. g. with H2S）, the numerical simulation preview on the release dispersion of the well＇ s blowout, as well as the emergency evacuation from the infected area. The release rate of H2S at a well - head can be taken as a classification indicator for identifying the hazard levels. If the blowout events range from 0.01 m^3 to 1.0 m^3 per second, they would be identified as those of level 3 whereas low hazard rates, such as from 1.0 m^3 to .5.0 m^3 per second, can be identified as level 2. The highest hazard events are identified as level 1 if the release events are over 5.0 m^3 per second. Public protection events may include the public safety protection distance from and the emergency planning zone around the natural gas well. The early warning forecast and the numerical simulation preview on the release dispersion should indicate the temporal and spatial distribution of H2S diffusion, as well as likely casualty hazards. At the same time, the emergency evacuation has to show the display of the dynamic changes of human movements on the roads and nodes. All in all, the information-control system should be an important means for safety and emergency management decision-making for high-sulphuric gas wells. Thus, it can be seen that the suggested system can be taken as a system framework, a database structure for displaying the functions and characteristics of the information-control s
