| Abstract: | The model of rare earth elements(REEs)transport and transformation in drab soil has been established.In accordance with characteristics of drab soil,this model was used in evaluating the process of REEs trasport and transformation in soil quantitatively by using some readily available inputs.It includes the chemical thermodynamic balance system of REEs,soil water physical characters and REEs flux in soil profile.The model simulation has been performed in the Scientific Field in the China Agricultural University,Beijing.Some predictions were found in fairly good agreement with the experimental data. |
