摘要
GIS作为一种先进技术,以其强大的制图和空间分析功能,在地学领域中得到了广泛应用.以成矿预测理论为基础,用GIS空间分析进行成矿预测并分为三步加以阐述:数据的采集与建库、GIS成矿预测空间模型的建立、预测靶区的圈定,重点介绍了建立成矿预测空间模型中的地质异常与找矿有利度分析.对西天山北部金、铜矿点进行了空间分析,探讨了在GIS平台上开展区域成矿规律及成矿预测研究的方法.
GIS as an advanced technology, with its powerful function of mapping and spatial analysis which has been widely used in geography field. This text takes mineral predication laws as foundation, and divided into three steps to describe how to using GIS spatial analysis to minerogenetic prediction, its application illustrated which includes three steps are： firstly ,collecting data and creating database; secondly, building GIS spatial model and delineating beneficial degree in study area; especially introduced relation of geology abnormality and beneficial minerogenetic, analysised the Cu. Au ore deposits in west Tianshan, discussed in GIS platform for effective minerogenetic law and prediction methods, it can provide more method and minerogenetic information for predication of ore deposit in the study area.
