摘要: 土壤中有益微量元素的含量受多种因素影响。根据不同地质背景特征，安徽省潜山县划分为7类成土母质。该文对不同成土母质、不同土壤类型进行了土地质量地球化学调查， 8 116件土壤样统计分析结果显示：潮土的Cu和Zn平均含量明显高于其他土壤类型，棕壤的Mo和Se平均含量也明显高于其他土壤类型；在相同土壤类型，不同成土母质之间微量有益元素含量的差异性较大；在不同土壤类型，相同成土母质体内有益微量元素的含量趋于一致。原位风化情况下，成土母质来源于地质背景区基岩风化，土壤中有益微量元素的丰缺取决于基岩类型；非原位风化情况下，成土母质如河流冲积物类母质，形成的各种类型土壤元素含量变化较大。部分土壤类型如潮土和棕壤中微量元素含量特征由土壤类型决定。以地质背景为基础的成土母质与土壤类型综合影响潜山县土壤有益微量元素的含量特征。Abstract: The content of beneficial trace elements in soil is affected by many factors. According to different geological background characteristics in Qianshan County, the soil parent materials could be divided into seven types, This paper conducts a land quality geochemical investigation on different types of soil and soil parent material, and the result of statistical analysis of 8 116 soil samples showed that no matter in what kind of parent material, the average content of Cu and Zn in tidal soil was significantly higher than that in other soil types, and the average content of Mo and Se in brown soil was also significantly higher than that in other soil types. In the same soil type, the content of trace beneficial elements in different parent materials was different, while in different soil types, the content of beneficial trace elements in the parent material of the same soil tends was same Under the condition of in-situ weathering, the soil parent material comes from the weathering of bedrock in the geological background area, and the abundance and deficiency of beneficial trace elements in the soil depends on the type of bedrock. However, under the condition of non-in-situ weathering, the content of various soil elements in the parent materials of soil, such as river alluvial materials, varies greatly. The characteristics of beneficial trace element content in some soil types such as fluvo-aquic soil and brown soil are determined by soil types. In conclusion, the characteristics of beneficial trace element content in soil are comprehensively affected by the parent materials and soil types in Qianshan County.
