【摘要】 利用M APG IS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。介绍了系统的实现思路和设计方法,并且较详细的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,与实际情形比较吻合,证明了该系统的正确性和可行性。更多还原

【Abstract】 The region characteristic and the space relativity of environmental geochemistry offer the possibility to unite geography information System with the environmental geochemistry.Geography can combine the space data management with the attribute data management and has the higher visibility.In this paper,making use of the reconstruction function of MapGIS,an environmental geochemistry information system is exploited,which includes the regional geology introduction subsystem,the attribution database management and analyse subsystem,the spatial database management and analyse subsystem.The realization and the design method of the system is introduced,especially the basic principle and the pivotal technique about GIS applying in the environmental geochemistry such as the buffer region, the contour,the shortest path,the water quality index,etc.,and the spatial database management and analyse subsystem is 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.更多还原
