| 摘 要： | 以黄河流域下游野外获得的土壤粒度和深度纵剖面试验资料为基础，分析了黄河流域下游不同土壤类型区、不同地貌单元的土壤粒级组成、元素在各粒级组中的分配特征和元素在土壤纵剖面中的含量、纵向变化规律，探讨了其在生态地球化学调查中的意义。确定了能代表区域内土壤主要物质组成的粒级范围，提出了本区生态地球化学调查的最佳样品筛分加工方案和表层、深层土壤样品采集的有效深度和层位。

| Abstract: | According to the grain sizes of soils and experimental data of the longitudinal depth sections gathered from the lower Yellow River valley,the paper deals with different soil type areas,different landform units,soil size distribution,distribution characteristics of elements in various grain sizes of soils and contents and longitudinal variations of elements at the longitudinal soil sections. The significance of soil grain sizes in ecological geochemical investigation has also been discussed. The grain size range that can represent the main material composition of soils in this region has been ascertained. Finally the paper proposes the best plan for sample sieving and processing in the ecological geological investigation of the region and the effective depth and horizon for collecting soil samples in the surface and deep layers. |
