皖西大别山区富锌土壤分布特征及成因分析

Distribution characteristics and genetic analysis of Zinc-enriched soil in the Dabie Mountain area, western Anhui province

通过开展皖西大别山区1/25万土地质量地球化学调查,发现研究区内土壤锌元素含量主要集中在71~150mg/kg,其中大于84mg/kg富锌土壤达到2808km^2,占到全区58.74%。富锌土壤主要呈大面积分布于区内北部岳西县-头陀镇及南部岳西县店前镇-太湖县寺前镇-宿松县柳坪乡,分布特征受区内地质背景、成土母质影响明显。此外,通过研究区内农产品和根系土中的锌含量特征,发现具有开发富锌农副产品的潜力。

By the Land Quality Geochemical Survey(1/250 000)in Dabie Mountain area of Anhui province,it was found that the content of zinc in this area was mainly concentrated at 71~150 mg/kg,of which more than 84 mg/kg of zinc- rich soil reached 2 808 km2,accounting for 58.74% of the whole area.The zinc- rich soil is dominantly distributed in the broad regions in Yuexi County- Doutuo Town in the north,and Dianqian Town- Siqian Town-Liuping Town in the south.The distribution characteristics are obvious influenced by the geological background and the parent material in the area.In addition,through the study of the characteristics of zinc in agricultural products and root soils in this area,it has been found to be the potential area for developing zinc-rich agricultural and sideline products.
