3S技术在国外火山减灾中的应用

在参考大量国内外有关应用遥感（ＲＳ）、地理信息系统（ＧＩＳ）、全球定位系统（ＧＰＳ）技术进行火山监测，预测及火山灾害评估等火山减灾文献的基础上，总结了国外火山减灾工作研究的现状和进展，提出火山减灾应大量应用遥感、地理信息系统和全球定位系统等高新技术，且指出未来山减灾工作的方向是综合、系统、实时、动态、立体化和可持续减灾。

Applications of 3S Technologies to Volcanic Disaster Mitigation in Foreign Countries

Based on large amounts of volcanic disaster mitigation literatures at home and abroad that introduce volcano monitoring,prediction and volcanic disaster assessment using the technologies of Remote Sensing (RS),Geographic Information System (GIS) and Global Positioning System (GPS),the paper sums up the present situation and developments of the volcanic disaster mitigation work in foreign countries;proposes that a lot of new and high technologies,such as Remote Sensing,Geographic Information System and Global Positioning System etc.should be used to volcanic disaster mitigation;points out that the direction of future volcanic disaster mitigation work is comprehensive,systematic,timely,dynamic,multidisciplinary and sustained disaster mitigation.
