摘要:

 土壤水热耦合模型的研究是20世纪50年代在等温水分运动模型的基础上发展起来的,与大气环流、水资源利用、农业及遥感技术的应用密切相关,具有广泛的应用价值,已经成为陆面过程研究中的重点。本文介绍了目前流行的几种土壤水热耦合模型及其特点,分析了这些模型在一些特定区域的检验效果及作用趋势,并讨论了土壤水热耦合模型存在的问题及未来发展方向。

Abstract:

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.

Key words: heat-moisture coupling, numericalmodels, research advances
