Research of the coupled heat-moisturemodelof soilwas developed in the 1950s based on the isothermalmodelof soilwater movement. It is closely related to atmospheric circulation, the use ofwater resources, agriculture and application of remote sensing technique, and italso increasingly became a focus in land surface process research. This paper introduces severalpopular coupled heat -moisturemodels of soil and their characteristics, and analyzes the test effects and the acting trend of thesemodels in some specific regions. Some problems atpresent researches and future development direction on the coupled heat-moisture model of soil are discussed finally.
