摘　　要：对首次开展的珠江三角洲、江汉平原、成都平原多目标区域地球化学调查资料进行对比研究,结果显示:土壤地球化学元素的分布在不同地区既有共性又存在差异性。共性表现为地球化学元素在土壤垂向剖面上的继承性、叠加性和渗透性,差异性则反映不同沉积来源、不同沉积环境的土壤地球化学特征明显不同。ComparatiVe study was performed on the data obtained by multi-objective regional geochemical survey carried out for the first time in the Zhujiang River delta, Jianghan plain and Chengdu plain. The results show that there are both general characters and differences in distribution of geochemical elements in soils in different areas. The general characters are manifested by the inheritance, overlapping and penetration of geochemical elements at the vertical section of soils, while the differences are marked by the marked difference in soil geochemical features in difference sediment sources and different sedimentary environments.
