| 摘 要： | 土壤水分运动参数的选取和确定是研究包气带中水分贮存和运动的基础.本文以河南驻马店亚粘土为例,进行了非饱和土壤水分运动参数的测定.通过将实测数据与经验模型拟合,将实验结果、计算结果和拟合结果进行了对比分析,发现所用的经验模型与实际数据吻合较好.研究结果表明选用的经验模型是可靠的,从而确定了土壤水分运动最优参数.

| Abstract: | The selection and confirmation of parameters in soil moisture movement is the basis for studying water storage and movement in the zone of areation. The paper took the loam in Zhumadian of Henan Province as an example, and carry out the measurement on parameters of unsaturated soil moisture movement. Through comparing the data of on-the-spot survey to the empirical model, comparing the experimental result, calculated result to the approximated results, the used empirical model is fitted well with the experimental result. The results shows the selected model is reliable and confirms the optimum parameters of soil moisture movement. |
