| 摘 要： | 通过对太原盆地地球化学取样中土壤浅、深层元素多重分形特征的详细分析研究，确定了8种微量元素（As、Cd、Cr、Cu、Hg、Pb、Zn、Ni）在盆地的背景区和异常区以及元素的分维值，并依据分维值对微量元素进行了分类研究。在此基础上，对其富集趋势进行了尝试性分析，认为土壤浅层、深层差异性大，浅层富集趋势强于深层。为太原盆地土壤质量评价提供了可靠的依据。

| Abstract: | 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. |
