| 摘 要： | 利用Van Genuchten模型对用砂性漏斗测量中砂的吸湿过程和脱湿过程土壤水分特征曲线进行拟合,结果表明实测曲线和拟合曲线吻合很好,并得出Van Genuchten模型中的残余含水量、特性参数α和n,模拟计算表明,中砂有αw=1.69αd的关系,为研究水分和污染物在非饱和土壤中运移问题提供土壤水分运动键参数. |
| 关 键 词： | 土壤水分特征曲线 Van Genuchten模型 吸湿曲线 脱湿曲线 |

| Abstract: | Soil water characteristic curve was measured with a sand column for both drying and wetting processes,and the data were used to fit the van Genuchten model.The fitted curve is in good agreement with the actual measurements,residual water content and other factors(such as and) used in the van Genuchten model were obtained.For the sand studied,.The results from this study may provide reference for research of water and solute movement in unsaturated soil. |
| Keywords: | Soil water characteristic curve van Genuchten model wetting curve drying curve |
