Abstract: Geographic Information System (GIS) technique provides a powerful tool for managing,manipulating,analyzing and displaying space related data set. The compilation of seismic zoning map requires a vast amount of spatially referenced data. Therefore,the application of GIS to the seismic zo￣ning work allows the users to take advantage of various functions of GIS into the seismic zoning work. This paper introduces briefly the procedure and results of GIS application in the compilation of the New Seismic Zoning Map of China (2001). The GIS Database of the New Seismic Zoning Map includes three sub-databases: 1. Sub-database for seismic environment and potential seismic sources,including: (1)Earthquake catalog; (2)Quaternary active faults; (3)Cenozoic basins; (4)Earthquake mechanism; (5)Geophysical anomalies and deep structure; (6)Seismotectonic provinces and zones; (7)Potential seismic sources. 2. Sub-database for earthquake ground motion and seismic attenuation,including: (1)Seismic intensity and isoseism; (2)Observed seismic intensity; (3)Strong ground motion. 3. Sub-database for the results of probability calculation of seismic parameters.

Key words: seismic zoning, seismic parameters, Geographic Information System

摘要： 编制全国性的地震动参数区划图,涉及到多个学科的大量与空间位置有关的信息,需要对海量空间数据进行有效的存储、处理与统计分析。GIS信息技术适用于存储、管理、分析与表述各种带有空间分布特征的信息。文中介绍了在中国地震动参数区划图编制工作中“GIS信息系统设计专题”的成果。该专题所设计的系统,可充分利用GIS信息技术的各项功能,对编制地震区划图所使用的各种数据从输入、编辑、处理、分析、图形绘制到输出进行系统的、科学的可视化分析与管理。中国地震动参数区划图GIS系统的数据库分为3个子系统1)地震环境及潜在震源区子系统;2)地震动基础资料及衰减关系子系统;3)地震动参数概率计算结果子系统。
