论述了微量元素在土壤中的迁移、存在状态,探讨了影响微量元素化学行为及生物有效性的主要土壤环境因素,分析了这些元素在土壤中形态转化的机制及平衡状况,为评价土壤中微量元素的变化,提高其生物有效性提供依据。
Transfer of trace elements and translate of element configuration in soil are described in this paper. In addition, transferring mechanism of trace elements and the status of balance for the elements are discussed, The purpose for the probing transferring mechanism for the elements will mainly focus on how to evaluate fertility of trace elements in soil and improve the validity of trace elements.
