中国花岗岩地理信息系统建设的探讨

讨论了中国花岗岩地理信息系统建设方案。在全面收集、综合、分析、整理中国花岗岩地质资料的基础上，对地质图属性信息进行合理的分类及编码，分别建立花岗岩的属性与图形数据，并在空间信息与属性信息之间建立正确的连接，运用计算机及其网络通讯技术，形成中国花岗岩地理信息系统，实现根据区域、地层、构造、岩石、矿产、地球物理、地球化学等属性对花岗岩地质图的信息进行灵活检索。在建立数据库的基础上，在Internet上建立中国花岗岩专业网站，使花岗岩地质信息的在线服务成为可能。

A discussion on the construction of Chinese granite GIS

The program of constructing Chinese granite GIS is discussed in this paper. On the basis of collecting, synthesizing, analyzing and coordinating Chinese granite geological information in an all_around way, the property information of geological map is to be reasonably classified and coded, and the property data and graphics data for granite are to be established and correctly connected respectively. With the computer and network communication technology, Chinese granite GIS will be finally constructed. Then, the establishment of Chinese granite professional website on Internet will provide online service. It is possible to search for Chinese granite geological information according to such keywords as spatial positions, strata, structures, petrology, mineral resources, geophysics and geochemistry.
