摘要
中国地震综合等震线图是编制中国地震动参数区划图的一张基础图件。本文以1991年版中国地震综合等震线图为基础,补充1980年以后破坏性地震等震线资料,使用地理信息系统软件ArcView编制了新版中国地震综合等震线图。并将新版图件与1991年版进行对比,分析了新版中国地震综合等震线图的主要特点。新版中国地震综合等震线图可为认识我国历史强震的烈度分布特征和地震构造条件提供帮助,它对于地震区划、国土利用规划以及防震减灾决策等也有重要的参考价值。
The comprehensive isoseismal map in China is a basic map for compiling the map of China’s ground motion parameters zonation.Based on the comprehensive isoseismal map in China published in 1991,supplementing the isoseismal data of destructive earthquakes since 1980,a new comprehensive isoseismal map in China is compiled with GIS software of ArcView.Comparing the new version with the 1991 version,the main characteristics of the new version are analyzed.The new version of China’s comprehensive isoseismic map can help to understand the intensity distribution characteristics and the conditions of seismic tectonics of China’s historical strong earthquakes.It also has important reference value for seismic zonation,land use planning,and decision-making on earthquake prevention and disaster reduction.
