中国典型矿床实物地质资料波谱数据库及其服务系统建设建议

随着地质工作地不断深入,各实物地质资料保管单位已积累了大量珍贵的实物地质资料,但其资料服务主要为传统的到馆观察、取样等。采用红外光谱等新技术方法充分挖掘实物地质资料内部蕴含的各类信息,建立波谱数据库,利用"地质云"开展在线服务,可有效地提高服务效率,降低服务成本。本文结合国内外相关工作现状、存在问题,面向服务需求,提出建设中国典型矿床实物地质资料波谱数据库,包括构建"国家-省级-基层单位"的三级数据汇聚、管理与统一发布机制,搭建"矿种-成因类型-矿床-钻孔-波谱数据"五级数据库组织体系,采用"2-3-4-5"的总体架构模式,即2条主线,3层分布式模型,4层数据体系,5个主体功能。本文旨在为有效提升我国实物地质资料数字化、信息化保管与服务水平提供切实可行的解决方案。

Suggestions on Construction of Spectrum database and Service system of Cores and samples from Chinese typical deposits

Along with the development of geological works, a mount of priceless cores and samples were captured by different levels of storage departments of cores and samples. But watching and taking samples are still main form of service all around in our country. There is a huge cost cut if we scan those cores and samples with reflectance spectrum and other later technologies and upload related data into Geo-Cloud for online services. A suggestion about constructing spectrum library of cores and samples of typical deposits in China which include 2 main lines, 3-layer Distributed System Model, 4-level data system and 5 main functions was made in this article based on analyses of current states, issues and requirements for improving digital, informational storage and services level in our country.
