摘要
在矿产资源定量预测中 ,单元是预测模型与地质信息联系的桥梁 ,是统计分析的基础。传统的规则网格单元划分方法虽然给矿产预测的计算机化带来了方便 ,但也存在许多问题。作者在本文中初步论述了在地理信息系统的支持下不规则地质体单元的划分方法 ,以及利用 GIS的空间数据分析功能提取出不规则单元中的地质信息。
In the quantitative prediction and assessment of mineral deposits, the unit acts as a bridge between the prediction model and the geological information, and it is also a base for the statistical analysis. Although traditional regular mesh unit division method has many advantages, such as easily to form the mesh unit by the aid of computer, there are many disadvantages as shown in the practice applications. This paper puts forward an alternative method supported by GIS to divide the study area. The method regards the irregular boundaries between the geological bodies and other polygons as the unit and extracts the geological information from the unit by using the spatial data analysis function of GIS.
