利用饱和多孔介质水热耦合运移数学模型，分析了流入河道的水库下泄低温水水位和水温对地表水地下水交错带温度场的影响规律。研究表明：在低温水下渗过程中，水热运移以热对流作用占主导，热传导、热弥散等作用较弱；河道水位升降明显决定着受影响的温度场区域范围大小；河道水温高低主要影响温度场各点温度的变化幅度。

The  influences of the level and the temperature of cold water in the channel released from reservoir on the temperature field of groundwater-surface water ecotone  is analyzed with mathematical models of coupled water and heat transfer in saturated porous media. The research shows that compared with thermal conduction and thermal blooming, the thermal convection plays a leading role in the transfer of underground water and heat during cold water infiltration. Water level in the channel determines the extent of the temperature field being affected, and water temperature mainly affects the  temperature variation  at each point in the temperature field.
