摘　　要：分析了影响采光量的主要因素(脊高、采光面、地理纬度、温室方位、日照时间等),根据温室内热量交换的平衡,建立了日光温室内温度数学模型,利用Matlab软件对模型进行仿真求解,动态模拟出设计参数对温室内温度的影响,并对不同参数的温度与实测值进行比较,相对平均误差为5.56%。Based on the main factors of the optical model in a greenhouse - ridge height, incident surface, geographic latitude, orientation, Sunshine times, back wall thickness, etc. a mathematical temperature model of a sunlit greenhouse was developed, using the calorie equilibrium theories of inside and outside heat exchange of the greenhouse. Corresponding Maflab 6.0 programs were deployed to simulate and analyze the effect of the parameters above. Comparing the results to real temperatures, the relative mean error is 5.56%, which indicates that the mathematical model can be used in greenhouse design.
