淮河流域环境地质调查信息系统的设计与实现

基于GIS二次开发，通过对项目数据资料整理与分析，设计建立系统内部数据库，结合控件以及组件开发技术建立淮河流域地质调查信息管理系统（HHEGData系统）。创建的HHEGData系统内部数据库——HWData将项目调查、测试、收集所有数据、图件以及文档规范整理录入，系统设计了两个主功能模块——属性数据库管理模块和空间数据库管理模块，根据项目资料类型进行更规范更便捷的检索，实现属性数据与空间数据双可视、多样查询，为提出地下水资源保护和可持续开发利用的对策建议提供信息支持。 Based on GIS secondary development and the project data organization and analysis, a system internal database was designed and built, which was used further and combined with the control and component technology to develop the environmental and geological survey information system in the Huaihe River Basin (HHEGData system). The developed system internal database (HWData) of the HHEGData system includes all the data, maps, and documents obtained from the project survey and testing. The design of HHEGData system includes two main function modules - attribute database management module and spatial database management module, which can provide more standard and more convenient data inquires based on project data type, and realize the dual visualization and various inquires of the attribute data and spatial data. The information system can offer technical and information support for the measures of protection and sustainable development and utilization of groundwater resources .
