摘　　要：建立了一维土壤高温蓄热热湿传递模型,采用控制容积法对模型进行离散处理,利用Matlab软件编程求解,计算分析了热源温度和土壤初始含水率对土壤温湿度场分布的影响,探讨了地下土壤热湿传递特性及水分迁移规律。A numerical model of one-dimensional heat and moisture transfer was established for high temperature heat storage in the soil. The finite volume method was used to deal with the model and Matlab was used as well for programming and solving the model. The effect of heat source temperature and initial soil volumetric water content（VWC） on soil temperature and VWC distribution were analyzed, the characteristics of soil heat and moisture transfer and the law of moisture immigration were discussed as well.
