Fractal characteristics of elements As , Cd , Cr , Cu , Hg , Pb , Zn and Ni contained in surface and deep-seated geochemical samples from Taiyuan basin were analyzed and studied in detail. The background sections, singularity sections and multifractal dimensions of these eight elements were determined, which were taken for the classification study. On such a basis, their concentration trends were tentatively analyzed. It is held that there exists considerable difference between the surface and deep-seated layers, and that the surface layer has stronger concentration trend than the deep layer. The result of this study provides a credible basis for soil quality assessment in Taiyuan basin.
