基于MapGIS组件式开发的河南省滑坡监测预警系统设计与实现

以河南省几处滑坡隐患点为研究对象,根据工程地质勘查与现场监测资料,基于MapGIS组件式开发技术和ZedGraph绘图技术设计开发了河南省滑坡监测预警系统。该系统使用MapGIS提供的控件和组件搭建了一个简易的、可交互的GIS平台,并在建立灾害监测点动态监测数据查询功能的基础上,通过9种常用的滑坡灾害预报模型,实现了不同滑动阶段下滑坡的预测预报,从而从时空上实现了对滑坡灾害的全面监测预警,同时通过SQL Server数据和MapGIS数据的结合以及MapGIS COM组件的应用,实现了从监测数据采集、计算分析到预警发布流程的自动化,为河南省滑坡灾害的防灾减灾工作提供了决策依据。

Design and Implementation of Landslide Monitoring and Early Warning Systemin Henan Province Basedon Map GIS Component Development

For several landslide hazards in Henan Province,this paper designs and develops the landslide mo-nitoring and early warning system based on the technology of MapGIS component development and ZedGraph graphics according to the engineering geological exploration and field monitoring data.The sys-tem uses the controls and components provided by MapGIS to build a simple and interactive GIS platform. With the function of querying the dynamic monitoring data of disaster monitoring points,the system applies nine common landslide prediction models which are suitable for different sliding stages of landslides,and implements a comprehensive monitoring and early warning for landslide hazards in both time and space. Through combination of SQL Server data and MapGIS data and application of the COM components in MapGIS,the system realizes the automatic process from monitoring data collection,calculation and analysis to early warning release.The system can provide decision-making basis for disaster prevention and mitiga-tion of landslide disasters in Henan Province.
