| 摘 要： | 覆盖区地球化学异常是由自然和人为因素引起的，在土壤垂直剖面上元素有多种分布类型，它反映了元素在土壤中迁移、演化及人为干扰的分布特征；通过对自然和人为污染的地球化学异常源追踪和评价，为环境污染治理和地区经济可持续发展提供决策依据。

| Abstract: | The overburden areas are restricted to those centralized and dense areas of human activities in alluvial plains, basins, river streams and coastal economic zones. The intensions of conducting multi-objective geochemistry survey in the overburden areas are to investigate and verify the soil elements and the contents and their distribution properties of the related geochemistry index,to provide important and fundamental geochemistry information for the eco-environmental estimation,resources evaluation and fundamental geological research.The geochemistry anomaly in the overburden areas is of both naturally and artificially origin.On the vertical soil sections,there are many types of element distribution types that reflect the element distribution properties in its course of migration,evolution and artificial disturbance in the soil.Through the trace and evaluation of the naturally and artificially polluted geochemical abnormal sources,some policy-making grounds are presented in the text for environment pollution treatment and the sustainable development of the local economy. |
