| 文章介绍了实体模型、场模型和混合模型三类空间数据模型及其相应的三维地质构模方法,列举了三维地质构模在矿产资源评价、城市地质、地下水资源评价方面的3个应用实例。在矿产资源评价中的应用是实体模型与场模型的集成,三维显示与检索采用实体模型,资源量估算和矿化分布预测采用场模型;在城市地质中的工程地质层状地质体建模采用多层DEM构模法,介绍了基于三维地层模型的剖切等应用分析;地下水资源评价中含水层组的三维建模采用剖面构模法,以水文地质剖面为建模数据源,辅以钻孔、含水层组底界埋深等值线、地表高程等值线等作为约束条件。 |
| 英文摘要: |
| This paper introduces three type spatial data models (the feature model, field model and hybrid model) and their modeling methods. Three application cases are listed: (1) mineral resources evaluation mode; (2) city geological model; (3) underground water evaluation model. In mineral resources evaluation mode the entity model and field model was integrated, three-dimensional entity model was used to display and retrieval, field model was used in reserve estimation and mineralization distribution prediction. In city geological model DEM modeling method was used to stratified geological; bodies in engineering geology. In underground water evaluation model hydrogeological sections are the main data source and hydrogeological borehole data, contour lines of aquifer group bottom depths the constraints. |
