Determination and Fitting of Soil Thermal Conductivity

本文介绍了土壤热参数在水热耦合数学中的应用以及土壤热导率的确定方法;并进一步采用Campbell经验公式拟合毛乌素风积沙土壤含水率与热导率的关系,结果表明Campbell公式的拟合程度较好。一方面给出了公式中各参数的取值,另一方面为研究毛乌素风积沙土壤水热耦合运移提供参考。

The paper introduced the application of soil thermal parameters in the coupled mathematics of water and heat and the determination method of soil thermal conductivity. Moreover,Campbell＇s empirical formula was further used to fit the soil moisture content and thermal conductivity of Mu Us aeolian sand,The results showed that Campbell＇s formula was well fitted. On the one hand,the values of the parameters in the formula were given,and on the other hand,it provided a reference for the study of the coupled water and heat transport of Mu Us aeolian sand.
