英文摘要Field investigation, sampling and element analyses were used to analyze the contributions of different surface processes on the heterogeneity of surface soils and the responses of vegetation elements in China's Otindag Desert. The analyzed results show that there are variations in the contributions of different surface processes on the spatial heterogeneity of the surface soils. In this region, the aeolian processes play key roles in the spatial heterogeneity of the surface soils, and the contributions of other processes, such as hydrological processes, dustfall deposition, anthropogenic pollution and underlying rocks, are lower than those of the aeolian processes. In addition, the analyzed results also show that the vegetation elements and communities respond differently to the surface soils. For the A. frigida community, the soil contents of Co, Mg, Sr, Pr, Nd, Sm, Eu, Tb, Tm, Y, In, La, and Ce may have close relations with community development, while the soil contents of Co, Cu, Ni, Sr, Pr, Nd, Sm, Tb, Y, In, La, Ce, and Bi may affect the development of the S. klemenzii community in the region. These results show that although surface processes play important roles in the heterogeneity of soil elements, the autogenic adaptability of the community may also result in the heterogeneity of the vegetation elements.
