在以往的研究中， 地震学家对地震灾害的分布规律做过大量工作， 然而灾害时空分布的分析主要停留在传统的图表描述上。随着计算机技术和地理信息系统的应用， 地震灾害的时空分布的分析方法在不断发展。人们可以利用 Ｇ Ｉ Ｓ 所具有的功能和地震灾害的特点，实现地震灾害空间信息的存贮、管理、检索、统计分析、自动制图和建立灾害的评估模型等， 使地震灾害时空分布规律的研究向深层次发展。本文阐述了玉溪地震减灾信息系统的作用、功能、主要内容、创新、特点， 以及应用举例。
In previous studies, seismologists have done a great deal of work on the distribution of earthquakes. However, the analysis of space-time distribution of disasters has mainly stayed on the traditional chart description. With the application of computer technology and geographic information system, the analysis methods of the spatial and temporal distribution of earthquakes are continuously developing. People can make use of the features of GIS and the characteristics of earthquake disaster to realize the storage, management, retrieval, statistical analysis of earthquake spatial information, automatic mapping and disaster assessment model so that the research on the spatial and temporal distribution of earthquake disaster To deep development. This article expounds the function, main content, innovation, characteristic and application of Yuxi earthquake disaster reduction information system.
