摘　　要：2024年1月23日乌什7.1级地震发生后,根据震后震害调查结果,并结合震区遥感影像、震源机制和发震构造绘制地震烈度图。在本次烈度图的绘制过程中,Ⅸ度地处山区,缺少强震台网的布设,故在确定Ⅸ度烈度圈时首次参考InSAR结果。通过对比震害调查结果和仪器烈度结果,发现二者吻合度较高,所以在本次确定烈度圈边界时参考仪器结果。本研究重点讨论在不同烈度区内各类房屋的破坏情况以及地震地质灾害现象,分析判定各类房屋震害特征。After Wushi M_(S)7.1 earthquake occurred on January 23,2024,the seismic intensity map was drawn according to the post-earthquake damage survey results,combined with the remote sensing image,focal mechanism and seismogenic structure of the earthquake area.In the process of drawing the intensity map,the IX degree is located in the mountainous area and lacks the layout of the strong earthquake network.Therefore,the InSAR results are referred to for the first time when determining the IX degree intensity circle.By comparing the results of earthquake damage investigation and instrument intensity results,it is found that the two are in good agreement,so the instrument results are referred to when determining the boundary of the intensity circle.This study focuses on the destruction of various types of houses in different intensity areas and the phenomenon of earthquake geological disasters,and analyzes and determines the characteristics of various types of house damage.
