层次分析法在青藏高原中西部航磁异常分类及找矿预测中的应用

层次分析是一种将难于定量化的复杂问题,逐层分解为一系列可定量化的简单问题,进而进行求解的数学方法。在青藏高原中西部航磁概查研究工作中,用层次分析法筛选局部异常,划分找矿远景区,取得了较好效果。

THE APPLICATION OF HIERARCHICAL ANALYTICAL TECHNIQUE TO THE CLASSIFICATION OF AEROMAGNETIC ANOMALIES AND THE ORE-PROSPECTING PROGNOSIS IN CENTRAL AND WESTERN QINGHAI-TIBET PLATEAU

The hierarchical analytical technique is a mathematical mthod with which one can decompose step by step a complex problem that can hardly be quantified into a series of quantifiable simple problems and then seek the solutions. During the aeromagnetic survey conducted in central and western Qinghai Tibet plateau, the application of hierarchical analytical technique to sieving local anomalies and classifying ore hunting prospect areas was proved to be fairly effective.
