In　order　to　satisfy　the　demands　of　employing　Geographic　Information　System　(GIS)　for　carrying　out　abundant　analysis　and　decision　making　in　the　planning　of　urban　hazard　prevention,　it　is　desirable　to　develop　a　decision-making　and　management　system　in　the　Quanzhou　and　Xiamen　Urban　Hazard　Prevention　Planning　Study.　This　paper　analyses　the　basic　structure　of　the　decision-making　and　management　system　for　the　planning　of　urban　hazard　prevention　based　on　ArcGIS.　In　comparison　between　two　different　ArcGIS　secondary　development　strategies,　a　similar　software　inclusive　framework-based　software　structure　of　the　decision-making　and　management　system　for　the　planning　of　urban　hazard　prevention　has　been　proposed　where　software　interfaces　and　their　realizations　for　the　C++　classes　and　the　main　functions　are　developed　and　introduced.
