论述了基于三维网络地理信息系统(GIS)的地质灾害监测预警系统的总体框架结构及特点,并对采用的信息采集组网与通信、时态GIS技术和基于多模型的地质灾害监测预测预警技术等关键技术进行了介绍。系统采用部署灵活、扩展性强的多层体系结构,运用地理信息技术、虚拟仿真技术和基于多用户并发的WEB异步服务技术,构建了融合三维地理信息功能与地质灾害预警预报业务功能的网络决策支持系统,实现了地质灾害信息采集、传输、管理、分析、决策、预警发布的一体化平台,系统已在丹江口库区投入试运行,可为我国地质灾害管理科学化,应急响应高效化提供参考和借鉴。
Abstract
The overall structure and features of a 3-D GIS-based monitoring and warning system for geological hazard are expounded. Key technologies including information gathering network and communication, temporal GIS, geo-hazard monitoring and warning based on multiple models are analyzed and introduced. The system with multiple layers adopts highly scalable structure and flexible deployment. GIS, virtual simulation, and WEB asynchronous service based on multi-user concurrent are also employed. Through the system, functions of information gathering, communication, management, analysis, decision-making, and warning are integrated. The system is applied to Danjiangkou reservoir as a trial. Finally, the research provides reference for the scientific management of geological hazards and emergency response.
