摘要： 本文概述了地震烈度遥感评估的思路和方法, 给出了遥感综合震害指数、 地面等效震害指数计算的模型和地震烈度估计方法。 利用2010年青海玉树7.1级地震发生后获取的主要地震灾区玉树县城区结古镇高分辨率航空遥感影像及其遥感震害解译结果和震后地震现场震害遥感比对科学考察成果, 进行了结古镇的地震受灾程度和地震烈度的遥感评估。 综合分析表明, 玉树县城区遥感评估的地震烈度为IX度, 与地面调查确定的地震烈度一致。 文章最后对结果进行了讨论, 表明遥感方法对应急烈度评估具有实用价值。

Abstract: This paper provides an overview of the ideas and methods of the assessment of seismic intensity based on remote sensing, describes the models to assess the remote sensing synthetic damage index and seismic intensity. With the data of damage information extracted by the authors from the high resolution aerial images in the earthquake-stricken areas (Jiegu town, Yushu City, Qinghai) of the 2010 MS7.1 Yushu earthquake, and the data obtained also by the authors through post-earthquake field investigation, the seismic damage level and seismic intensity have been estimated. Analysis of the results shows that the seismic intensity in the Yushu City is estimated as IX through the remote sensing assessment method, which is consistent with the result assessed according to the ground surveys. The results are discussed in the last part of the paper.

Key words: Building seismic damage, Synthetic seismic damage index, Seismic intensity, Remote sensing assessment, The 2010 Yushu earthquake
