摘 要：
根据能量平衡原理,构建了日光温室土壤热环境模拟模型。该模型全面考虑了与日光温室内表层土壤进行热能传递的5大因素,包括日光温室内表层土壤吸收的太阳短波辐射,与空气的对流换热,与日光温室结构和作物的长波辐射换热,与深层土壤的热传导及土壤蒸发的潜热交换。利用北方干寒地区典型结构的日光温室对模拟模型进行了试验验证,结果显示模拟值与实测值比较吻合,相关系数大于0.85,相对误差小于10%。试验证明构建的北方干寒地区的日光温室土壤热环境模拟模型是适用的。

摘 要：
Based on the principle of energy balance,A dynamic simulation model of thermal environment of soil in Chinese solar greenhouse was established. The influenced four factors correlative with shortwave radiation absorption by soil,convection from indoor air to soil,longwave radiation absorption from wall,roof,plant and covering film to soil,conductive heat transfer from upper to lower soil layer and soil evaporation were included in the simulation model. The experiment was carried out in the Chinese solar greenhouse in the northern drought cold to validate the correctness of the simulation model. The results showed that the soil temperature simulated agreed well with the measured data,correlation coefficient greater than 0. 85 and the relative error is less than 10%. The experiment results proved that thermal environment model of soil in Chinese solar greenhouse in the northern drought cold is correct.
