摘要
城市活动断层探测成果图件集是近年国家活动断层探测科学工程项目开展以来形成的重要资料,其集成编绘将有助于今后地震地质研究和防震减灾的开展。城市活动断层探测成果图件集包括20个城市的1:250000区域地震构造图与1:50000活动断层分布图。文中系统详细地探讨了区域地震构造图与活动断层分布图地图信息的组织与表达、设计思想、制图综合、图例规范与编制过程。最后,还简要介绍了基于ArcGIS平台的计算机规范化制图过程。
China Earthquake Urban Active Fault Surveying Project is a national important scientific and engineering project in recent years.Its map achievement,which includes 1：250,000 regional seismotectonic map and 1： 50,000active fault distribution map of twenty cities,is an important integrated document and will be utilized in seismological and geologic research,protecting against earthquake,and relief of disaster.However,these maps are not drawn in uniform standards.As a result,there is lack of normalization in stratigraphic division,map information expression and map layout.The lack of standardization will lead to further problems when publishing and utilizing these documents because of the diverse information expression. This paper discusses the design philosophy,data scheme and expression,cartographic generalization,illustration standard and mapping procedure of the 1：250,000 regional seismotectonic maps and 1： 50,000 urban active fault distribution maps.The map information is from urban active fault databases,which are based on ArcGIS Geodatabase technique,and the mapping procedure is based on ArcGIS mapping template technique.Therefore,the paper also introduces the mapping procedure in ArcGIS software and references the information organization in urban active fault database. Since cooperation among industries,universities and geological research institutions becomes increasingly prominent,the mapping achievement of active fault surveying is in urge of standardization and normalization.The work in this paper is based on years of work of active fault survey project.We have collected suggestions and advices from first-line technological staff to scientific experts,and then revised our work in many details.It is expected that this work can promote the standardization and normalization of the active fault map achievements.
