【Objective】 The research studied the relationship between thermal conductivity and water content of four kinds of typical lithologics in Mu Us Sandy Land. 【Method】 According to different lithologic characteristics and sediment environment, we suggested a new test method. Meanwhile we measured thermal conductivity under different water contents using the JW-Ⅲ heat-flow meter. 【Result】 By analyzing the differences between thermal conductivity and water content in Mu Us Sandy Land, and making use of the new model provided by campbell and the author, the measured thermal conductivities of all kinds of lithologics and fitting error were analyzed. 【Conclusion】 According to the analysis, the new model suggested by the author was used to fit the measured thermal conductivity-water content curves. The model can greatly reflect the characteristics of parameters, the related coefficients of measured values and fitted values are bigger than 0.97.
