【摘要】 随着信息化时代的到来,特别是地理信息系统和网络技术在地质领域应用的深入,人们对不同来源、不同内涵的地质数据构建数据模型日益重视起来。本文依托新疆和中亚邻国地质矿产信息集成与成矿预测课题,以GIS为数据平台,结合国内与国外的地质数据模型,构建大地构造相图空间数据模型,为成矿规律与矿产预测工作提供有效的数据支持。大地构造相图作为成矿地质背景研究的基础,凝聚了人们对地质理论的研究成果和对地质过程的理解。对巴尔喀什-准噶尔地区大地构造相图进行分析,从大地构造空间序列和大地构造时间序列两个角度来建立地质概念模型,基于信息科学的思想,使用Geodatabase数据模型,讨论大地构造相图的要素类、属性表及其之间的相互关系,构建基于信息科学思想的巴尔喀什-准噶尔地区大地构造相图空间数据模型。实现依据限定条件,对基础地质图件的数据进行属性添加、信息融合、概括等,通过简单的空间分析生成相关的图件,将传统的以“绘成”为主的编图方式,转变为由基础地质图件来“生成”为主的成图方式。依据大地构造相图空间数据模型建立大地构造相图的空间数据库,使空间数据的属性和可视化之间保持完全的一致性,大地构造相图成为能够表达多角度、多层次成矿地质背景的“活”图,从而实现大地构造相图的智能化表达。更多还原

【Abstract】 With the advent of the information age, geographic information systems and network technology is increasingly being applied to the depth of geological areas. There is increasing attention to build up the data model of geological data which is the data from different sources and different connotations. In this paper, based on geological minerals information integration and mineralization forecast topic in Xinjiang and the Central Asia neighboring country, taking GIS as the data platform and unifying domestic and the overseas geological data model to construct the spatial data model of tectonic facies map. It can provide the effective data support for the metallogenic regularity and the mineral prediction.Tectonic facies map is foundation of metallogenic geological background research and cohere with the understanding of the geological theory researching and the geological processes. According to study the tectonic facies map of Balkhash- Junggar region, the article establishment geology conceptual model from two aspects which are tectonic setting and tectonic evolution. Based on the idea of information science, the article using Geodatabase data model and discussing feature class, attribute table and their mutual relations to construct tectonic facies spatial data model of Balkhash - Junggar region that based on the idea of information science. According to limited conditions, to deal with the basis of geological maps data through the method of adding attributes, information fusion, generalization, etc. By the simple spatial analysis, the basis of geological maps has been changed into the relevant maps. Finally, we can transform the tradition way that give priority to“draws”the map to the new way that through the basis of geological maps“produce”the map.The establishment of tectonic facies map spatial databases based on tectonic facies map data model, it can guarantee complete uniformity between spatial data’s attribute and the visualization. Tectonic facies map can be a“live”map and it lively express multiple perspectives, multi-level, Thus realizes intellectualized expression of tectonic facies map.更多还原
