摘　　要：地质环境数据具有多源、异构、复杂等特点。为更好地发挥地质环境数据的作用,针对不同类型的地质环境数据,融合数据格式转换、数据互操作和直接访问三种数据整合方法,提出了一种地质环境数据的集成方法。该方法依托地质环境信息服务平台,实现了矢量空间数据、遥感栅格数据和属性数据的集成整合。最后,将该方法应用到1∶20万区域水文地质空间数据库,并对具体集成整合过程进行说明,最终将集成后的数据入库到地质环境信息服务平台,提高了数据应用价值。Geological environment data have features of multi-sources,heterogeneous and complex and so on.To ensure geological environment data play better roles data integration methodwas summed up for different types of geological environment data using a combination of three methods,which included data format conversion,data interoperability and direct access to data. Relying on geological environment information service platform（ GEISP）,data integrations were finished for vector spatial data,raster data and attribute data with this method. Finally,taking 1 ∶ 20 0000 regional hydrogeological spatial database as an example,the specific data integration process was illustrated and data value was improved with the integrated data storage to GEISP.
