摘　　要：针对统计分析法、人工判图法等常规方法在矿业权布局研究中的局限性,本文提出了基于ArcGIS的格网分析法,并应用于大冶-阳新整装勘查区矿业权布局变化情况研究工作。分析结果显示,位于最小预测区范围内的大多数探矿权均处于勘查阶段停滞状态或者是缩减勘查面积。与传统分析法相比,格网分析法能够将不规则变化的矿业权数据转换为规则数据,有利于实现前后多期矿业权信息数据的自动关联与对比,便于凸显关键信息,能够大幅提升研究工作效率。Aiming at the limitation of conventional analysis methods in the study of mining rights layout,such as statistical analysis and manual interpretation,this paper presents a grid analysis method based on ArcGIS,which has been used in the study of the changes of mining rights layout in the Daye-Yangxin equipped exploration districts.According to the analysis results,part of prospecting rights in the prospective area of mineral deposits did not improve exploration phase,and the others reduced exploration area.Compared with the conventional methods,the grid analysis method is able to turn the irregular data into orderly data,such as the prospecting rights data.At the same time,the new method can achieve the automatic correlation of data and compare the data extracted from the minning rights database in different periods.Critical information could be more readily represented on the grid diagram.This can greatly enhance the work efficiency.
