湖州表层土壤全氟含量分布及评价

Distribution and Evaluation on Total Fluorine Contents in Surface Soils of Huzhou

为揭示湖州表层土壤中全氟的空间分布特征及其与其他元素间的相关性,测定分析了湖州市表层土壤的全氟含量,按照土壤全氟指数法评价该地区土壤质量。结果表明,湖州市表层土壤中全氟含量范围在111～883mg/kg之间,均值448 mg/kg,98.4%的表层土壤全氟含量处于正常水平,湖州市表层土壤中全氟含量与Li、Ga、Be、Cs含量密切相关且呈正态分布。

In order to disclose the spatial distribution of total Fluorine in surface soils of Huzhou and the relevance between total Fluorine and other elements, the contents of total Fluorine in soils were determined and the quality of soils was evaluated by total fluorine index method. The results showed that the contents of total Fluorine in soils were 111 ~ 883 mg/kg,with average concentration of 448mg/kg, 98.4% of the area were in the normal status. The contents of total Fluorine in surface soils of Huzhou had a closely positive correlation with those of Li,Ga,Be and Cs in soils.
