摘　　要：分别从等温和非等温水盐动态模拟以及覆盖边界层三个方面 ,以秸秆覆盖条件下土壤水、热、盐耦合运动规律模拟研究为重点 ,介绍了 50年代以来土壤水热盐数学模拟的研究成果 ,并简要论述了有关模型的特点及今后的发展方向。According to the theoretical and practic al simulation of isothermal and non-isot hermal movement of water and salt,and bo undary with mulch,this paper introduces the status of studying advances in simul ation and coupled modeling on moisture m ovement,heat transfer,and salt transport in soils,especially the soils with stra w mulch.Based on summarizing above,the f eatures of concerned models and desirabl e development are discussed briefly.
