Model driven architecture （MDA） has tried to give a way to share the programmers＇ diligent work,and unified modeling language （UML） is used to standardize the process of software development. With the base of unified data criterion architecture and information code architecture, the geologic hazards are analyzed and geologic information rnodds are preliminarily designed in this paper. By efficiently and visually analyzing and processing of geologic information with spatial distribution characteristics, the
system are validated with good prediction and preparedness of geologic hazards. Key words:urban fundamental geologic; MDA; GIS; three - dimension emulation and stimulation; hazard preparedness
