利用GIS技术和RS技术减灾防灾

减灾防灾是一项需要多学科知识融会贯通的长期工程。灾难的发生是由多种因素造成的，在分析管理的时候，需要大量的数据源，因而，分析过程相当地耗时耗费。近年，由于能够高效提供详细、精确的相关数据．GIS技术和RS技术在灾难管理方面应用广泛、发展迅速，遥感技术提供灾情数据．GIS技术通过模型将各种数据有机地整合起来，包括空间数据、非空间数据、属性数据，使它们在灾难管理的各个阶段发挥不同的作用。

Disaster Prevention and Mitigation using GIS and RS

Disaster prevention and mitigation is a complex task involving all kinds of scientific knowledge and experience,which allows a long-term implementation.As many factors can play important role in the occurrence of the disastrous events,substantive data sources are required in the process of disaster management.The increase availability of RS data and GIS during the last decades has created opportunities for a more detailed and rapid analysis of hazards.The proper structure of information system for disaster management should be presented to tackle and manage the disaster.The remote sensing and GIS database can be used to create elaborate and effective Disaster Management Information System.
