海南省土壤中硒含量及影响因素分析

Analysis on Content of Se in Soil of Hainan Province and Its Influencing Factors

对海南省不同市县土样中的硒含量进行了分析。结果表明,海南土壤总硒量变幅为0.055～2.231 mg/kg,平均含量为0.765mg/kg,土壤硒分布具有明显的地域分异性。土壤硒含量受成土母质、质地、pH值和土地利用方式等的影响,其中成土母质与土壤硒含量的关系较密切。

Se content in soil samples from different City-county of Hainan Province was analyzed.The results showed that the variable amplitude of total Se content in Hainan soil was 0.055-2.231 mg/kg and the average content of Se was 0.765 mg/kg.The distribution of Se in soil had obvious regional differentiation.The content of Se in soil was affected by parent material,soil texture,pH value and land use patterns etc,and the relationship between parent material and Se content in soil was more close.
