摘    要：根据矿产资源评价的特点,将GIS不同层次的空间分析方法应用于矿产资源评价中,通过对预测区的研究确定影响成矿的主要因素;运用GIS的图形分析确定参与评价的因子,生成各专题图层,建立专用的评价数据库;此外,运用层次分析建模方法确定了各因子权重,建立基于层级权重叠加模型的评价方法,实现了与GIS系统的集成,并最终圈定成矿预测靶区.实践结果表明:将GIS技术应用于矿产资源评价不仅拓展了GIS的应用领域,而且改变了传统的矿产资源评价方法,为矿产资源评价提供了新的思路和手段.

Abstract: The application of spatial analysis of different levels formineral resource estimation is introduced. The predict-ed area is studied to confirmmain elements affecting the forming of mineral deposit, factors and special map needed inthe estimation are confirmed by analyzing and processingthe graph data and the special estimated data base are built. The estimated model is established according to analyzing and modeling by AHP to ascertain the weights of estimating factors and the model is combinedwith GIS, finally the favorable regions are chosen. With the application of GIS in mineral depositresource estimation, it is proved that the study area of GIS is extended, and changed the traditional estimation method. GIS provides newtools and means for mineral resource estimation.
