备注

《辽宁省1:100万数字地震构造图》以ArcGIS为平台,以《1:400万中国地震构造图》和《辽宁省1:50万地质图》为底图,结合近年来1:25万、1:20万、1:5万地质调查新成果和城市活断层探测等有关资料,采用新方法、新规范(GB/T 36072-2018、DB/T 73-2018、GB/T 985-2015)[1-3]编制而成。图中对于辽宁地区地震活动性要素、地震构造基础条件、地层要素、主要构造要素进行了深入探讨,重点建立了42条活动断裂数据库,并增加了依兰—伊通断裂、密山—敦化断裂、金州断裂、鸭绿江断裂等研究新成果。为辽宁省地震构造研究及地震危险区划分提供参考依据。

Based on ArcGIS,taking 《1:4 million earthquake structural map of China》 and 《1:500 000 geological map of Liaoning Province》as references,collected the new geological survey results of different scales(1:250 000,1:200 000,1:50 000)and the urban active fault detection in recent years,the paper used new methods and norms to draw up the 1:1 million digital seismotectonic map of Liaoning Province. In the figure,seismicity elements,basic conditions of seismic structure,stratigraphic elements and main structural elements in Liaoning Province are deeply discussed. The paper focused on the establishment of 42 active fault databases,and added new research results such as Yilan-Yitong fault,Mishan-Dunhua fault,Jinzhou fault,Yalujiang fault,etc., which provide reference for seismotectonic research and seismic risk zone division in Liaoning Province.
