环境地球化学信息系统的建立及其应用

The Establishment and Application of Environmental Geochemistry Information System

利用MapGIS的二次开发功能,自主开发了一个环境地球化学信息系统。该系统具有区域地质介绍子系统、属性数据库管理分析子系统、空间数据库管理分析子系统。为此,介绍了系统的实现思路和设计方法,并且较详细地阐述了空间数据库管理分析子系统,最后将该系统运用于湖北黄石地区的环境地球化学研究工作中,对该地区的环境地球化学数据进行查询分析和质量评价,与实际情况比较吻合,证明了该系统的正确性和可行性。

The author made use of the reconstruction function of MapGIS to exploit a environmental geochemistry information system including the regional geology introduction subsystem, the attribution database management and analyze subsystem, the spatial database management and analyze subsystem. The realization and the design method of the system has been introduced, and the spatial database management and analyze subsystem has been elaborated. Then the system has been applied to the region of Hubei Huangshi to analyze and quality evaluates to the environmental geochemistry data, which has proved the validity and feasibility of the system.
