摘要
利用遥感数据分析汶川Ms8.0地震灾区建筑物的倒塌、道路桥梁的损毁以及次生地质灾害分布情况,以《中国地震烈度表》为标准进行烈度判断,绘制了汶川地震烈度图。总结了利用遥感手段绘制地震烈度图的经验和存在的问题。
Through remote sensing （RS） the damage information of a large area can be obtained in spite of traftic condition, so using remote sensing data to map seismic intensity distribution is of great advantage. Seismic intensity distribution is mapped on the basis of the Chinese Seismic Intensity Scale by analyzing the damage of constructions, roads and bridges, and earthquake-induced geological disasters. Finally, experiences and problems of mapping seismic intensity distribution by RS data are summarized.
