摘　　要：将建立地球化学图形 数据库过程分为已建立常规地球化学数据库和未建立常规地球化学数据库,其主要区别是采样点位是否具有地理位置坐标。以未建立常规地球化学数据库的情况为例,介绍了利用MAPGIS软件建立和管理地球化学图形 数据库的思路、过程和方法,并简单介绍了利用建立的图形数据库进行检索和地球化学专题图件制作的方法。According to the sampling points which have or have not coordinates of geographic localities, this paper has divided the process of establishing geochemical graphics-database into two conditions: the condition that the general geochemical database has been established and that the general geochemical database has not been established. With the condition that the general geochemical database has not been established as an example, this paper not only describes the idea, process and methods for establishing geochemical graphics-database, but also discusses the method of retrieving and drawing geochemical thematic maps with MAPGIS software based on the established geochemical graphics-database.
