| 摘 要： | 地震烈度包络线通常用地面调查宏观地震影响和破坏现象来划分。本文介绍在完成国家“八五”科技攻关项目中，突破常规调查方法，采用遥感与ＧＩＳ技术，在室内针对震害遥感影像完成震害分类分级，进而通过人机对话完成地震烈度包络线的快速生成的方法和技术。运用该技术以唐山地震区作模拟试验表明：遥感与ＧＩＳ技术快速生成的高烈度包络线，不仅使大量实地调查变为室内遥感应用分析，时效提高了１０倍，而且其轮廓形状更趋客观实际。

| Abstract: | Earthquake isoseismal is usually determined based on the macroscopic earthquake affection and damages observed in the field.This paper presents a new method using remote sensing and GIS techniques.The seismic hazards were classified by aerial images and then isoseisms were produced in GIS database.Tangshan earthquake in 1976 is a case study and the results show that isoseisms produced by remote sensing and GIS techniques are more effectife. |
