On the basis of comparing with single-element anomaly method��taking 1 /200��000 geochemical exploration data of Baishan area in Jilin as the example��the authors studied the spatial quantitative combination anomaly model��established the medium-large scale factor Pan-Kriging model in this area��applied DEM to express 3D element spatial distribution model and gave out geological interpretation with multi-elements spatial distribution and spatial quantitative combination anomaly methods�� The results showed the multi-spatial quantitative combination anomaly method was higher in accuracy��better in internal structure and correlation and more in geo-information than traditional single element method��especially the three-dimension expression of DEM was more intuitive��
