3S技术在地质灾害详细调查中的应用研究进展

Research Progress on the Application of 3S Technology in the Detailed Investigation of Geological Disasters

3S技术是遥感系统(Remote Sensing System,RS)、全球定位系统(Global Positioning System,GPS)、地理信息系统(Geographic Information System,GIS)的统称,作为一个统一的有机体,具有强大的空间信息处理以及分析能力。我国是地质灾害发生十分频繁且损失极为严重的国家之一。在地质灾害详细调查中,3S技术具有十分强大的功能。通过GPS定点调查、遥感解译、GIS室内分析,判别地质灾害体的发育规律与发育类型,为地质灾害防灾减灾等提供了较为翔实的基础数据,并且可以为应急救援提供技术支撑。

3S technology is a collective name for the remote sensing system(RS),global positioning system(GPS),and geographic information system(GIS),and as a unified organism,it has strong spatial information processing and analysis capabilities.China is one of the countries where geological disasters occur frequently and the losses are extremely serious.In the detailed investigation of geological hazards,3S technology has very powerful functions.By GPS fixed-point survey,remote sensing interpretation and GIS indoor analysis,it distinguishes the development law and type of geological hazard bodies,which can provide more detailed basic data for geological disaster prevention and mitigation,and provide technical support for emergency rescue.
