摘要
利用GIS技术对地质灾害信息进行快捷发布、预警与决策,是地质灾害管理与防治的有效途径之一。基于地质灾害预警与领导决策的需求,对结合ArcIMS地图服务与A jax技术的地质灾害预警系统的目标、结构、功能、数据模型与数据库进行了分析与设计,探讨了系统开发所涉及的关键技术。最终完成了基于A jax模式的广东省地质灾害预警系统的开发,实现了地质灾害相关信息的分析,灾害等级划分与预警,以及灾害信息的发布。
As one of effective approaches of geological hazard management and prevention,the GIS techniques can support the information quick publishing,early-warning of geological hazard and decision making.Based on the requirements of leader decision and geological hazard early-warning,the target,structure,function,data model and database of a geologic hazard early-warning system which is mainly based on the ArcIMS map service and the Ajax technique are analyzed and designed,and the involved key technologies are described.The Ajax-based geologic hazard early-warning system of Guangdong province are developed ultimately,which realizes geological hazard relative information analysis,hazard levels classification and early-warning,and hazard information publishing.
