| 摘 要： | 断裂和某些特殊的岩体等地质要素通常与成矿作用密切相关,寻找其空间位置与成矿的关系是一项值得研究的内容,但目前尚缺乏定量分析的有力工具。这里利用证据法和MAP-GIS的空间分析功能,实现了线缓冲区与矿点分布的空间关系的定量分析,介绍了应用原理和实现的技术流程,讨论了实现的关键技术,并以云南维西为例展示了应用效果。

| Abstract: | Some geological factors such as fault and some special rock mass are usually closely related to mineralization. Searching for the relationship between mineralization and the position of the geological factors in space is a worthy study work, but there is lack of effective tool for quantitative analysis. This paper realizes quantitative analysis of the relationship between line buffer and mines spatial distribution with weights of evidence method based on MAPGIS, and introduces the method principle and techn... |
