矿产资源预测评价数据库的设计与实现--以桂西-滇东南锰矿为例

The Design and Implement of Prediction and Assessment for Mineral Resources Database-in Case of Manganese Deposit in the Western Guangxi and Southeastern Yunnan Province

以桂西-滇东南锰矿为例,介绍了矿产资源预测评价数据库的建立方法。在分析地质数据的多元性、分布性、多尺度、遗留性等特点的基础上,设计了矿产资源预测评价数据库的整体框架,主要包括:1)"纵向分层、横向分块"的数据库层次结构;2)以目录、文档、图件、表格的数据分类方法建立的"树状目录"式的数据库模型;3)符合"树状目录"式地质资料检索习惯和管理模式的基于角色的数据库访问控制。结合桂西-滇东南锰矿预测评价的应用,提出了基于统一"数据服务接口"的异构空间数据库和基于B/S和C/S混合模式的数据库系统架构,为基于GIS的锰矿成矿规律、找矿模型与综合评价研究提供了统一的、标准化的数据平台支撑。

Taking manganese deposits in western Guangxi and southeastern Yunnan of China as example, the prediction and assessment database for mineral resources is introduced in detail. Based on analysis of characteristics of geological data, such as multi-source, distribution, multi-scale and＇legacy, the global architecture of mineral resources prediction and assessmeut database is proposed finally. That includes： 1 ） level-lengthways arid block- breadthways structure of database arrangemeot; 2） tree-catalogue database model, which is classified as directory, document, map, table; 3 ） role based database assess control according to tree-catalogue quecry and management of geological data. By the application of manganese one prediction and assessment in western Guangxi and southeastern Yunnan of Cbiua, the heterogeneous databases based on same data service interface and the hybrid database system arehitecture of browser/server and client/server are proposed, which supply uniform and standardized data platform support for the studies of metallogenetic regularities, prospecting model and synthesized assessment of mineral resources based on GIS.
