活动断层探察的快速制图技术研究

A RAPID MAPPING SYSTEM IN CHINESE ACTIVE FAULT SURVEY PROJECT

活动断层探察作为有效减轻地震灾害的一项行业基础性科研工作,其系列专题图件是探察工作成果直观表达的重要手段。文中在分析近年来活动断层探察图件生产技术的基础上,从图件标准化和软件开发2个方面对活动断层探察快速制图技术进行了研究。所研究的这一快速制图技术已应用于正在开展的活动断层探察工作,并获得了规范、高质量的专题成果图件。文中探讨的图件快速产出流程标准化、软件功能设计对于其他基于GIS软件的制图系统设计具有一定的参考价值。

Active fault survey,which is one kind of fundamental researches for reducing disaster risk from earthquake,has been implemented by multiple governmental agencies since the early 1990 s in China.Chinese government sponsored some active fault survey projects these years. These researches and projects use a series of thematic maps to describe their processes,results and achievement. Since geography information science was introduced in late 1990 s and applied since 2000 s to these active fault survey projects,seismologists and experts began to draw thematic maps by this new technology.A convenient and fast way for seismologists and experts to produce atlas of active fault survey products is an important accelerator to achieve these projects.This paper studies on the rapid methodology of producing active fault survey atlas,which is basically built on the processes and contents of active fault projects in recent years,and introduces the methodology on two aspects of standardization and software development. This study has been applied to the ongoing active fault survey projects,and resulted in more effective process,normative data and beautiful atlas. Thus these researches will be easier to be used in future application such as publication,internet sharing,and city development. This methodology has reference value to similar map-producing system in standardization and software development.
