| 摘要: |
| 应用有限差分法对非饱和土壤中一维溶质运移模型数值求解，模拟了土壤水分运动和溶质运移的动态过程。以实测数据验证了模拟结果的合理性与有效性。为保证数值模拟正确进行，给出确定离散步长dx和dt的三个准则。 |

| Numerical Simulation of One-Dimensional Solut Transport in Unsaturated Soil |
|
|
| Abstract: |
| One-dimenional solute transort model was numerioally solved with finite-difference method.And the dynamic procedures of solute transport and soil water
movement were simulated.Also,the rationality and validity of simulated results have
been verified by measured data.Furthermore,three oriteria for determining the discrete
steps dx and dr were put forward to make the simulation correctly carryied out. |
| Key words: finite-difference method,numerical simulation,solute transport,unsaturated soil,descrete steps |
