| 摘 要： | 全国铀矿资源空间数据库的建设是开展全国铀矿资源成矿规律总结及潜力评价的研究工作的重要前提,为今后开展矿产勘查的规划部署研究奠定了扎实的信息基础,有利于积极开展矿产远景调查和综合研究,科学评估区域矿产资源潜力。本文主要介绍了全国铀矿资源空间数据库建模的方法、步骤,并将空间数据库中的图层划分为地理类逻辑层、基础地质类逻辑层、铀矿地质类逻辑层、物化遥逻辑层、整饰逻辑层共五个主类,最后详细阐述了空间数据库中的信息编码问题——图件编码、图层编码及属性表编码。

| Abstract: | The national Uranium resource spatial database is a basic database for national Uranium resource potentiality assess- ment.The building of database is prerequisite to the Uranium geology comprehensive research,which lay a solid information foundation for Uranium exploriation.Firstly,this paper introduces the method and process of Modeling in brief.Secondly,it discusses a design of the spatial layer division,that include five parts:geography logic layer;basic geology logic layer;Uranium geology logic layer;geo- physical exploration,geochemical exploration and remote sensing logic layer;decoration logic layer.Finally,the coding is studied chiefly,which is composed of the following three parts:map coding,layer coding and attribute table coding. |
