| 摘 要： | 水安全具有空间地域性.以辽河流域为例,阐述了基于GIS空间技术的水安全预警的逻辑过程.根据系统目标与原则,初步设计了系统的信息采集、查询与检索、因子评价与分析、动态预测与预警和系统指导管理功能;给出了系统的客户机-浏览器-服务器三层网络结构;构建了数据库.此系统的设计为及时掌握水安全的状态,发布预警信息,适时采取必要的调控措施等提供了科学依据.

| Abstract: | Water security is of spatiality and regionality. Logical process of early warning system of water security based on GIS is expounded taking Liaohe River for an example. System functions that involve information collection, query and search, assessment and analysis, dynamic prediction and early warning, guide and management are designed primarily according to its aim and principle. The client-browser-server network structures are designed. Database constructions are explained. This design provides the scientific gist for mastering water security states, issuing early warning information and taking essential measures. |
