| 摘 要： | 以土壤水动力学为理论基础,以原状砂壤土为例,进行了室内非饱和土壤水分运动参数的测定.通过实测数据与经验模型Van Genuchten的拟和,对试验结果和拟和结果进行了对比分析,发现计算值与实测数据吻合较好.结果表明选用的经验模型是可靠的,确定的非饱和土壤水分运动参数是合理的.

| Abstract: | In this paper the experiment of the parameters for unsaturated soil water movement by experimental method in laboratory was carried out based on the theory of soil water dynamics and a case study of sandy clay loam.By observing the field data and fit values of Van Genuchten empirical model,it is found that the values of computation agree with the experimental data fairly well and also the result of selective empirical model is feasible,the determination of soil water movement by experimental method in laboratory is reasonable. |
