摘要
针对地学数据特点 ,研究了地理信息系统二次开发的多种模式 ,选择Arc Info地理信息系统作为地学信息系统的二次开发平台 ,采用Arc Info提供的开发环境进行开发工作 ,建立地学信息系统 .将专家多年找矿经验与计算机高精度计算相结合 ,依据地学信息提取方法及成矿影响因素 ,利用GIS的叠加分析、缓冲区分析等多种方法 ,对地学数据进行成矿预测分析 ,圈定成矿远景区 ,并将中间成果或最终成果绘制成所需要的专题图件 ,为进一步找矿提供了一种新的途径 .
The application of geological information system in ore predictions is discussed. The paper selects Arc/Info as the development system of geoscientifical information system from all kinds developmental models of GIS for geoscientifical data′s characteristics, builds the geoscientifical information system in the developmental environment of Arc/Info, analyses the geological information, and predicts the ore-regions and turns primary or final results into topic maps by combining experts′ experience and computers′ rapid and precise computing, analyzing factors controlling mineralization, and by using the methods of extraction of geological information and GIS′s overlaying and buffering analysis. Geological information system provides a new method for ore predictions.
