根据对重庆地区土壤中微量元素含量的研究认为,微量元素概率分布类型在全土和单一的土类、土属中是有明显差异的,同一元素可以为不同的分布型,微量元素概率分布型可因各成土因素的变化而改变,但主要受成土母岩的岩石类型,岩相岩性特征所控制。本文拟就这一问题提出我们粗浅的认识。 According to the study of trace elements in soils in Chongqing area, the probability distribution types of trace elements in the whole soil and single soil, soil genus are significantly different, the same element can have different distribution, trace element probability distribution type Due to changes in the factors that make up the soil, it is mainly controlled by lithology and lithofacies characteristics of the parent rocks. This article intends to put forward our superficial understanding of this issue.
