This　paper　describes　the　design　of　a　distributed　architecture　to　support　an　interactive,　interoperable,　and　collaborative　forest　fire　fighting　simulation　using　IEEE　standard　1516　-　High　Level　Architecture　(HLA).　Based　on　the　Run-time　Infrastructure　(RTI)　services　which　are　specified　in　HLA　and　C++　application　programming　interface　(API)　of　the　RTI,　The　distributed　virtual　fire　fighting　environment　provides　a　practical　foundation　to　enhance　interactivity,　interoperability　for　distributed　simulation.　Users　can　build　new　federation　application　by　the　way　of　the　goal　system　reorganization.　The　key　techniques,　such　as　FOM/SOM　design,　system　structure,　running　mechanism　of　simulation　system　are　discussed.　From　the　system　implementation　and　experimental　results,　the　proposed　HLA　distributed　architecture　is　a　practical　and　scalable,　and　applicable　for　a　large-scale　of　fire　fighting　simulation.
