Study and implementation of fire sites planning based on GIS and AHP

Urban fire is a hidden danger for city safety. Therefore, the overall layout of fire fighting facilities is an important part of fire control planning in cities. This study combines the method of GIS and AHP together. The paper, which fully considers the complicated data and their mutual influence, makes full use of spatial analysis, data processing and query. Planning and analysis will be more flexible and universal by utilizing this method, and the complexity of spatial location selection can be decreased considerably, which consequently may overcome the casualness and uncertainty of subjective site selection. And finally, the approach satisfies the planning requests of some related fire fighting department to a certain degree.
