Abstract： Accurate predictionof emergencymaterial demand is crucial for enhancing China's earthquake emergencyrescue capabilities.Byconstructinga prediction model basedon the Back Propagation Neural Network，this study selects earthquake magnitude，tieinethethquakeicetertesityisicortiicationlevelartquakefrecastingopuatiosity andaectedareaasinputlayereuronswiththefectedpopulationasteoutputlayerneuron，achievingprecisepredictionof earthquakecasualties.Furthermore，byintegratingtherelationshipetweenthenumberofaffectedpeopleandthematerialdemand， thedemandforcriticalemergencymaterals（suchasdrinkingwaterandclothing）afteranearthquakeisestimated.Troughepiical analysis，teefectivenessand practicalityofthis modelinpredictingtheafected populationandemergencymaterialdeandare verified.
