摘　　要：给出了描述温棚系统中传热问题的数学物理模型及计算方法，并进行了实验研究。模型中考虑了气象环境参数、土壤的热湿物性以及塑料棚膜的太阳光学性质和热辐射特性，可预报温棚内空气和土壤中的温度和含混量的分布及变化规律。模型的数值模拟结果与实测值在数值和变化趋势上符合得较好，从而表明模型的正确性与可靠性。In this paper, the heat transfer topics in greenhouse have been studied.A mathematical model has been developed in order to predict the diurnal temperature variation of the soil surface, plastic film and enclosed air, as well as the soil temperature and moisture regimes in the greenhouse. The model takes into consideration of environment condition, soil thermophysical characteristics, and solar optical and thermal radiative properties of the plastic film. Calculated temperature profile is compared with observed one in experimental field plots. The result shows good agreement between the calculated values and measured data.
