A Knowledge Base System to Support Emergency Response of Geo-hazards under the conditions of Extreme Snow and Ice Disasters

Rapid and effective emergency response of geo-hazards is an important means to reduce disaster losses. Geo-hazards under the conditions of extreme snow and ice disasters are more complicated than conventional geological hazards. Therefore there's urgent need to build a knowledge base system for emergency response on geo-hazards under the conditions of extreme snow and ice disasters (KBS-ERG/ESID). Based on the analysis of specificity of geo-hazards and emergency response under the conditions of extreme snow and ice disasters and in accordance with the targets of knowledge base system, we put forward and elaborate a layered system architecture of KBS-ERG/ESID, which includes knowledge base layer, core control layer and graphical user interface layer. Then, some geographic information system (GIS) components are introduced into the system architecture due to the needs of displaying and analyzing spatial data when necessary. Finally, the operation steps of KBS-ERG/ESID are introduced by showing some critical system interfaces; meanwhile the effectiveness of the KBS-ERG/ESID is demonstrated.
