中文摘要：

汶川Ms8．0地震科学考察数据库存储了大量的野外调查数据，主要包括野外地质观测点、地表破裂带、震区第四纪断层的展布及其活动性地质观测点、古地震探槽、断错地貌测量等数据，以及搜集来的地层数据、汶川地震及其余震、重新定位余震、历史强震等数据。文中利用ArcGis将这些野外数据进行了录入、编辑、分析和制图输出，初步构建了一个包含基础地震地质信息的汶川地震科学考察数据库，实现了数据的空间位置和属性特征的综合管理，可根据需要对相关专题的数据进行查询、分析和处理，并绘制了汶川地震构造图及地表破裂分布图，为灾后重建避让带的确定提供了依据，为进一步构建汶川地震地理信息系统奠定了数据基础。

英文摘要：

The geodatabase of scientific investigation of Wenchuan earthquake stores many field investigation data, such as the data of field geological survey sites, the surface rupture belts, the Quaternary faults in the earthquake region, paleoseismological trenches, folds, etc. Moreover, it includes some collection data,such as strata data, the catalog of the Wenchuan mainshock and aftershocks, the relocation catalog of aftershocks of the Wenchuan earthquake, the catalog of historical strong earthquake. The field data are recorded, edited, analysed, mapped and output with ArcGis, a powerful function in Gis software. The geodatabase of scientific investigation of Ms8. 0 Wenchuan earthquake was initially established, which includes the basic seismological information and realizes the integrated management of spatial location and attribute information. Data can be queried, analyzed and processed for the need of the correlation analysis of the data. Seismic tectonic map and surface rupture map can be drawn with the geodatabase,which can provide the basis for the determination of safety distance from the risky seismic rupture zones in post-disaster reconstruction and for the construction of the Wenchuan earthquake geographic information system.
