摘要
为了研究大棚内外空气热量的物质交换的机理，该文把用在大玻璃温室的让布鲁温室动态模型应用于小塑料大棚。此模型考虑了温室内三层土壤、作物层、空气层、覆盖物和保温幕之间的传导、对流、太阳辐射和热辐射以及潜热交换，在此基础上进行了在不同气候条件下模拟的实测结果的比较分析。其结果表明，模型达到较高精度。
In order to clearly understand the mechanism of heat and mass exchanges between the interior and exterior air of a plastic tunnel greenhouse, the Gembloux Greenhouse Dynamic Model (GGDM ) used for the large glasshouses was applied to small plastic tunnel in which the conductive, convective, solar and thermal radiative as well as latent heat exchanges among 3 soil layers, vegetation, interior air, cover and thermal screen were taken into account. The comparative analysis between simulation and measurement was carried out under the different climate conditions. The results of validation show that the high degree of accuracy and reliability of the model is reached.
