在GIS技术环境下开展资源定量评价,实现资源评价工作的自动化、数字化、智能化是矿产资源勘查与预测的重要发展趋势.为了给地质勘查与预测人员、定量建模人员、GIS分析与操作人员提供共同研究和技术讨论平台,提出了在矿产资源预测全过程使用的建模技术.介绍了建模技术的基本概念、空间模型建立、图形建模技术以及建模技术在矿产资源定量预测中的应用,介绍了GeoDAS GIS中的建模技术基本功能以及建模技术在空间对象相关分析、证据(信息)图层提取、不规则地质单元划分、预测后验概率绘制等矿产资源预测工作中的应用实例.应用结果表明,建模技术为地质预测人员、定量建模人员、GIS操作人员开展综合研究和空间决策提供了公共的平台,有助于实现模型的共享和操作过程的自动化.
In the GIS technology environment to carry out quantitative evaluation of resources to achieve resource evaluation automation, digital, intelligent mineral resources exploration and forecasting is an important trend.In order to geological survey and forecasting personnel, quantitative modeling, GIS analysis and operation staff Provide a platform for common research and technical discussions and put forward the modeling techniques used in the whole process of mineral resources prediction.The basic concepts of modeling technology, the establishment of spatial models, the techniques of graph modeling and modeling are introduced in the quantitative prediction of mineral resources Application, introduces the basic functions of modeling technology in GeoDAS GIS and the application of modeling techniques in the prediction of mineral resources such as spatial object correlation analysis, evidence (information) layer extraction, irregular geologic unit division and prediction posterior probability mapping Examples The application results show that the modeling technology provides a common platform for the geological forecasting personnel, quantitative modeling staff and GIS operators to carry out comprehensive research and spatial decision-making, and helps to realize the sharing of the model and the automation of the operation process.
