【摘要】 地质灾害监测预警是提升主动应对地质灾害能力的重要手段。文章分析了第一代、第二代地质灾害预警模型主要特征,建立了基于多元线性回归的地质灾害预警模型,并将模型与地理信息系统(geographic information system,GIS)叠加,实现了气象雨量信息动态可视化方法。以此为基础,采用GIS、数据库及网络等技术研发了地质灾害监测预警系统,并以安徽省为背景进行示范应用。结果表明该技术方法可行,系统具备一定的可靠性,能为地质灾害减灾防灾决策提供一定的技术支撑。更多还原

【Abstract】 Geo-hazards monitoring and early warning is an important means to enhance the ability to actively respond to geo-hazards. In this paper, the main characteristics of the first and second generation geo-hazards early warning models are analyzed, a geo-hazards early warning model based on multivariable linear regression is established, and the model is superimposed with geographic information system(GIS) to achieve a dynamic visualization method of meteorological precipitation information. On this basis, a geo-hazards monitoring and early warning system is developed by using GIS, database, network and other technologies, and the demonstration applications are carried out in Anhui Province. The results show that this method is feasible, and the system has certain reliability and can provide certain technical support for the decision-making of the reduction and prevention of geo-hazards.更多还原
