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 on 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

    衛星遙感技術在減輕自然災害中發揮了十分重要的作用，但也不得不指出，衛星遙感技術在防震減災工作中，無論在國內或國外均尚未得到有效的應用.這一方面固然是由於地震事件十分復雜，地震孕育和發生的規律尚未搞清，難以發揮衛星遙感技術的作用，另一方面也由於可以使用的衛星遙感技術的解析度還不夠高，重復觀察的周期長，限制了這一技術在防震減災工作中的應用.有鑒于近年來衛星遙感技術有了新的進展，使其有可能在防震減災中發揮特殊的作用，本文旨在對衛星遙感技術在防震減災工作的應用，對它的可行性、有效性、經濟性和與此相關的科學技術問題進行探討，使這項技術能在防震減災領域早日得到應用，以促進我國防震減災工作的發展
