沾化冬枣产地的土壤地质地球化学背景研究

Background Research of Soil Geological Geochemistry in Zhanhua Winter Jujube

以生态地球化学理论为指导,利用沾化冬枣产地生态地球化学调查的基础数据,系统研究了沾化境内表层土壤元素的分布特征、组合特征及剖面特征,并在此基础之上深入探讨了沾化地区表层土壤形成的地质背景。研究结果表明,沾化地区在接受黄河冲积物之后还受到了后期地质作用的改造。受黄河冲积物、湖泊湖积物及人为污染的共同作用,形成了境内独特的地球化学特征。

Under the guidance of ecological geochemical theory,the fundamental data of ecological geochemical survey in Zhanhua was used,and the features of distribution,the combined characteristics and its section was studied systemly within top soils in Zhanhua,and geological background formed of the top soil in Zhanhua was explored deeply based on all of the above data.The results showed that Zhanhua area was reformed because of geological role in the late stage after the Yellow River Basin alluvial things were accepted.The unique geochemistry characteristics was formed because of the comprehensive effects of Yellow River Basin alluvial things,the lake alluvial things and man-made pollution.
