采用GIS无缝集成技术实现区域地下水环境质量评价系统

基于MapInfo和VB、VC等高级语言开发的环境质量评价系统,通常具有图形数据和属性数据的存储分离和操作不同步的不足,以致缺少对空间数据编辑的智能化处理能力。为克服不足,以某地区地下水环境质量的评价系统的开发为例,通过在MapInfo平台上无缝集成MapBasic应用程序,构建了基于MapInfo的区域地下水环境质量评价体系。该系统的实际应用与现有的同类系统相比较,表明可满足多种评价模型和方法,不仅能实现对区域地下水环境质量快速、高效评价,更重要的是具有对空间数据编辑的智能化处理能力,实现了对评价结果及其相应属性数据的同步操作,更加方便了客户的使用。

Construction and Application of Regional Groundwater Environmental Quality Evaluation System Based on GIS

Environmental quality evaluation systems based on the integrations of MapInfo and VB,VC or other advanced programming languages usually have the disadvantage of separate storage and non-simultaneous operation of spatial data and attribute data.This makes such systems lack intelligentized functions of compilation of spatial data.For the purpose of avoiding the disadvantage described above,taking the application of Nan Si Hu environmental quality evaluation as an example,constructs a MapInfo-based regional underground water quality evaluation and management system through integrating MapBasic applications into MapInfo platform seamlessly are presented.Compared with recent similar systems,this system not only carries out underground water evaluation by different ways,but also can compile spatial data efficiently and realize the simultaneous operation of spatial data and attribute data,all of which provides convenience for users.
