文章根据１９９６年在中国栾城农业生态试验站观测的田间试验资料，分析了土壤水分和土壤－大气界面对麦田水热传输的抑制和加速作用。对于显热和潜热输送，土壤水分起决定作用，土壤水分越小，显热通量越大，潜热通量越小，反之亦然。只在土壤水分较小时界面厚度对显热和潜热输送作用较大。对于土壤热输送，界面厚度起决定作用，界面厚度越大土壤热通量越小。分析还发现６０ｃｍ深处土壤水势与叶水势和大气水势的相关系数较其它深度处的土壤水势大。０～６０ｃｍ土层是确定土壤水分运动对界面水热传输影响的一个良好的指示层
Based on the field experiment data observed in Luancheng Agro-Ecological Experimental Station in China in 1996, the paper analyzed the inhibition and acceleration of soil moisture and soil-atmosphere interface on water-heat transfer in wheat field. For the sensible and latent heat transport, soil moisture play a decisive role, the smaller the soil moisture, the greater the sensible heat flux, the smaller the latent heat flux, and vice versa. Only when the soil moisture is small, the interface thickness has a great effect on the sensible and latent heat transport. For soil heat transport, the interface thickness plays a decisive role, and the larger the interface thickness, the smaller the soil heat flux. The analysis also found that the correlation coefficient between soil water potential and leaf water potential and atmospheric water potential at 60cm depth was larger than that at other depths. The 0 ~ 60cm soil layer is a good indicator for determining the influence of soil water movement on the interface hydrothermal transport
