摘　　要：在地学领域中,为了利用Arc/Info软件的空间分析、查询和可视化功能,以便对地学信息进行分析和提取,地学信息的导入是很关键的一步。Shapefile是Arc/Info支持的数据模型,这里对地学资料转换成Shapefile的几种途径进行了讨论,指出存在的问题和局限性,并给出了一种通过编程将数据文件转换成Shapefile文件的方法。该方法具有灵活、简单的特点。In geoscientific field, in order to apply the spatial analysis, inquiry and visualization functions of the Arc/Info software, so as to analyze geoscientific data and extract information from them, an important step is to load geoscientific information into Arc/Info. Shapefile is a kind of datum model that Arc/Info supports. Some methods of transforming data into shapefiles are discussed in this paper and their existing problems are pointed out. Besides, a new transforming method based on programming, is also presented, which shows flexibility and simplicity.
