地质灾害预警预报及信息管理系统应用研究

Application study on early warning/forecast and information management system of geological disaster

根据调查,江西省地质灾害的诱发因素主要是降雨,因此,通过总结前人关于地质灾害预报预警的研究,提出了一套应用降雨资料对地质灾害进行预报预警的预警流程,并建立预警及信息管理系统。该系统采用空间数据库引擎技术管理海量滑坡、地质、地貌、降雨等数据及地质灾害的文档等资料。系统基于WebGIS技术,实现了地质灾害预报预警图的发布、信息查询、空间定位、空间叠加和地质灾害预警预报信息反馈等功能。

Rainfall is the main inducing-factor of geological disaster in Jiangxi Province. This paper summarizes the research on geological hazards and proposes a method for the rainfall-induced landslides prediction. A system of forecasting and early-warning geological hazards were developed based on this method. The system manages enormous relative data which includes landslide data, geologic data, geomorphologic data, rainfall data and documents of geological hazards via spatial database engine. Based on WebGIS technology,the system implements and provides following functions ： issue of prediction map of landslide hazards probability, information query, spatial localization and spatial overlapping, forecasted information feedback and so on.
