摘　　要：近十年来松原震区地震频发,且地震震级≥4.0级地震较多。利用松原市城市活断层探测和吉林地震灾害风险普查数据,结合松原地区近十年来的地质构造新认识和地震活动数据,依据地震行业制图标准DB/T 72-2018《活动断层探察图形符号》和DB/T 73-2018《活动断层探察1:250000地震构造图编制》,使用ArcGIS地理信息制图平台,编制了松原震区主要断层分布图。该成果图对于后续在该区域开展地震灾害成因研究,对于抗震设防、防范地震灾害风险等研究都有着重要价值。In the past ten years,earthquakes have occurred frequently in the Songyuan earthquake area,and there are many earthquakes with magnitude≥4.0.Based on the urban active fault detection in Songyuan City and the seismic disaster risk survey in Jilin Province(1∶250000 seismotectonic map of Jilin Prov⁃ince),combined with the geological conditions of Songyuan area and the distribution of seismic activity in the past decade,according to the seismic industry mapping standards DB/T 72-2018“Active Fault Explora⁃tion-Graphic Symbol”and DB/T 73-2018“Active Fault Exploration 1∶250000 Seismic Structure Map Com⁃pilation”.And using the Arcgis geographic information mapping platform and the latest data,prepared the distribution map of main faults in Songyuan earthquake area.This map plays an important role in the followup research on the causes of earthquake disasters in the region,seismic fortification and earthquake disaster risk prevention.
