防震减灾中卫星遥感技术应用分析

卫星遥感技术在减轻自然灾害中发押了十分重要的作用，但也不得不指出，卫星遥感技术在防震减灾工作中，无论在国内或国外均尚未得到有效的应用。这一方面固然是由于地震事件十分复杂，地震孕育和发生的规律尚未搞清，难以发挥卫得遥感技术的作用，另一方面也由中以使用的卫星技术的分辨率还不够高，重复观察的周期长，限制了这一技术在防震减灾工作中的应用。有鉴于近感技术的分辨率还不够高，重复观察的周期长，限制了这一技术在防

Application of satellite remote sensing technology in earthquake disaster reduction

With the rapid development of satellite remote sensing technology, it has been widely applied in national economics and martial area, in particular, in the field of natural disaster reduction, for examples, in forecasting and controlling of flood, preventing of forest-fire, monitoring of landslide and debris flow and so on. Regretfully, as we understand the satellite remote sensing technology are rarely applied both at home and abroad for earthquake disaster reduction. It is because that on the one side, earthquake is a very complicated natural phenomenon with its indistinct genesis mechanism and occurrence of very low probability and oil the other side, the resolution of satellite remote sensing image is too low and satellite repeat period is too long that constrain this technique to be used in earthquake disaster reduction. This paper intends to address the application, practicability and other relative scientific-technical and economic issues, of satellite remote sensing technology in reducing earthquake disaster, it is believed that the earlier use of satellite remote sensing technology in China will provide a more effective and economic vehicle to minimize the future earthquake losses and also successful experiences to the world communities.
