The sunlight greenhouse in China not only has excellent energy-saving advantage, but also costs little for construction and maintenance. The objectives of this study are to establish the, thermal environmental and structural design optimization and construction regularization for the sunlight greenhouse. Experimental measurements and theoretical analysis were carried out to quantitatively explain the thermal environment of the sunlight greenhouseAfter developing the basic model, the modified mathematical model was developed to predict thermal environment of the sunlight greenhouse, supposed that cucumber crop was cultivated. The calculated value for the inside air temperature agreed with the measured one very well, and the resulting IA of it was 0.97. It was concluded that the mathematical model developed here had sufficient accuracy to analyze the effect of the sunlight greenhouse structure on the inside air temperatureIn Beijing, Changchun, and Shenyang, detailed measurements on micrometeorology in the sunlight greenhouse were carried out to analyze the thermal environment of the greenhouse. Inside air temperature was higher by 10℃ on average than the outside air temperature without heating during the night at the coldest period The percentage of the floor soil and north wall were 75 and 18 percent on average, respectively, in the total of heat discharge during the night, and it was shown that those two parts had critical role for retaining warmth of the greenhouse air temperature during night

我国日光温室不仅具有优良的节能优势，而且建设和维护成本低。本研究的目的是建立日光温室的热环境和结构设计优化和施工规范化。通过实验测量和理论分析定量解释了日光温室的热环境。建立了基本模型后，建立了修正的数学模型，以种植黄瓜作物为前提，对日光温室的热环境进行了预测。内部空气温度的计算值与测量值非常吻合，所得 IA 为 0.97。结论：本文建立的数学模型具有足够的精度来分析日光温室结构对室内气温的影响。在北京、长春、沉阳等地对日光温室微气象进行了详细的测量，分析了温室的热环境。最冷时期，夜间不加暖时，室内气温平均比室外气温高10℃。 夜间排热量中，地面土壤和北墙平均分别占75％和18％，这表明这两部分对温室夜间气温的保温作用至关重要。
