摘　　要：在2016年9月23日四川理塘M_S4.9、M_S5.1级地震应急处置与烈度勾画工作过程中,显示出地震现场背景信息,对应急处置等工作具有重要作用,巴塘断裂和理塘断裂之间这一地区,可能有一组雁行排列方式的张性正断层,易发生震群型、双震型地震。另外,在高寒地区特殊地理环境下,可依据当地历史地震的研究成果和震源机制等相关资料,快速判定发震构造,辅助绘制地震等震线。On September 23-（rd）, 2016, the MS4.9 and MS5.1 earthquakes respectively occurred at Litang county of Sichuan province. During the process on the emergency disposal and intensity sketch, the background information on post-earthquake field has an important function. Batang fracture and Litang fracture both exist in the area, and it is possible that a group of extensional normal fault with en echelon arrangement will be formed,and also the earthquake of swarm earthquake type and double earthquake type will occur easily. In addition, in the high and cold areas with the special geographical conditions, the historical research results on local earthquake and earthquake mechanism data concerned can be used as basis to determine seismogenic structure and assist to sketch the isoseismal of earthquake field.
