遥感与地理信息系统在自然灾害研究中的应用

THE APPLICATION OF REMOTE SENSING AND GIS IN THE NATURAL DISASTER STUDY

灾害是人类面临的最严重的威胁。本文从现代遥感技术与地理信息系统（ＧＩＳ）的构成和特点出发，论述了遥感与ＧＩＳ技术在减灾活动，包括预警、评价和辅助决策中的重要作用。在综合考虑现有各项技术的基础上，设计了以遥感信息为基础建立自然灾害信息系统的总体设想．

Disaster is a serious challenge that the mankind is faced with. Based on the characteristics of Remote Sensing techniques and GIS,it is discussed in detail that these techniques play a very important role in the natural hazard mitigation activities,such as early warning, real-time monitoring,quick assessing and decision making.Having thought over current technologies,the author designed an information system for monitoring and assessing of natural hazards tising Remote Sensing and so on.
