基　　金：the Key Project ofDirectors Fund of Earthquake Agency of Inner Mongolia Autonomous Region in 2018(2018ZD05);Special Task of Training of Yong Scholars of Seismic Network in 2017(20170606);the Key Youth Task of Earthquake Emergency in 2016,China Earthquake Administration(CEA_EDEM-201605);Major Science and Technology Projects in Inner Mongolia Autonomous Region in 2016(Research,Development,Popularization and Demonstration of Earthquake Prediction and Early Warning Technology in Key Areas) 摘　　要：Attenuation relation of seismic intensity is fitted by using 152 complete isoseismic lines from65 earthquakes which were greater than MS4. 0 from 1940 to 2015 in Inner Mongolia and neighboring regions. Meanwhile,based on the difference of land form and geological structure characteristics,the study area is the divided into eastern,western and central.The intensity attenuation relationships are established separately by using the LM( Levenberg-Marquardt) method and elliptic attenuation model. Comparisons are made by using the earthquake affecting field model of North China and computed results. The analytical study shows that the relation obtained represents the features of earthquake damage distribution in the areas well,and has positive meaning to guide loss assessments immediately after a destroyed earthquake. 关键词：SEISMIC Intensity EARTHQUAKE AFFECTING field INNER Mongolia LEVENBERG-MARQUARDT ATTENUATION relationship
