Forest is a finite resource and fire prevention is crucial work. However, once a forest fire or accident occurs, timely and
effective fire-fighting is the only necessary measure. The aim of this research is to build a computerized command
control system based on WEBGIS to direct fire-fighting. Firstly, this paper introduces the total technique flow and
functional modules of the system. Secondly, this paper analyses the key techniques for building the system, and they are
data obtaining, data organizing & management, architecture of WebGIS and sharing & interoperation technique. In the
end, this paper demonstrates the on line martial symbol editing function to show the running result of system. The
practical application of this system showed that it played very important role in the forest fire fighting work. In addition,
this paper proposes some strategic recommendations for the further development of the system.
