Abstract: Based on ArcGIS and MapInfo software,we digitized the active tectonic map(1:4000000)of China,which was compiled and revised by Academician Deng Qidong,and built the spatial database of active tectonics of China. The database integrates rich active tectonic data,such as earthquake catalogue with magnitude above 6,active faults,the Quaternary basins,active folds and their associated attribute parameters,and implements the scientific and effective management to these active tectonic data. At the same time,the spatial database joins the spatial map data and its associated attribute data together,which implements the data query between spatial feature and its attribute parameters and also makes it possible to do spatial analysis with different data layers. These provide much convenience for earthquake study and engineering construction institutions to use these data in practical application.

摘要： 以ArcGIS和MapInfo为软件平台,对邓起东院士多年来潜心研究和汇总的中国活动构造数据进行了数字化处理,采用统一的坐标系统、一致的投影方式和合理的数据库逻辑结构建立了中国活动构造空间数据库,实现了活动断裂、活动盆地、活动褶皱等活动构造及其各类相关参数的有效管理和系统集成,实现了图形数据和属性数据的相互查询,为各地震相关研究部门和工程建设部门利用这些数据提供了极大的方便。
