摘　　要：通过对数字高程模型数据(DEM)进行水文及空间分析,提出确定水系沉积物化探取样快速定位方法,并建立空间分析模型。在新疆达坂城铜矿区应用表明:新方法可满足不同比例尺水系沉积物化探勘查工作,具河流分级合理、化探测量点定位准确、多元信息综合利用和精确部署野外工作等优势。In this paper, in order to improving the efficiency in geochemical exploration,in connection with the shortcomings of the traditional sediments geochemical exploration positioning method,based on ArcGIS platform,by the Hydrological analysis and Spatial analysis to the digital elevation model data（DEM）,a new quick positioning method is proposed and discussed,and the spatial analysis model is built for this method.ln Dabancheng copper area,this research shows that the new method can meet different scales in geochemical exploration,and has four advantages,such as rationality in river classification,accuracy in geochemical exploration positioning,comprehensive utilization of multiple information and exact disposition in field works.
