Abstract: Objective]Sunlight greenhouse construction directly influences the ability to intercept solar radiation.[Method]In order to improve the utilization of solar radiation in solar greenhouse energy,based on the characteristic of solar radiation distribution and transmission theory of solar radiation intensity in different regions,the study took Urumqi area in Xinjiang as an example,the sun light intercepted by the front slope roof of sunlight greenhouse as the evaluation index,in combination with the time of solar radiation,the dynam-ic change law of the geographical position of solar greenhouse,using Energy Plus simulation software to analyze the construction of the optimum orientation of sunlight greenhouse in this area.[Result]The results showed that during the most unfavorable growth period of crops growing in winter in Urumqi area(1 1/1 ~2/28 ),the best orientation was southwest 10°.[Conclusion]This paper presents a method for the construction of solar greenhouse,which is based on the simulation and calculation,and is verified by the method of measurement and simulation.The model provides methods and theoretical guidance for the rational construction of solar greenhouse,which could not using the criteria and parameters simply to applied in solar greenhouse construc-tion in various regions.

摘要： 【目的】研究日光温室建造朝向直接影响日光温室截获太阳辐射的能力。【方法】以新疆乌鲁木齐地区为例，以日光温室前坡屋面截获太阳进光量最大为评价指标，结合太阳辐射随时间、日光温室所在地理位置动态变化规律，运用Energy Plus能耗模拟软件，研究该地区日光温室建造最佳朝向。【结果】乌鲁木齐地区冬季作物种植最不利生长期（11月1日至翌年2月28日），日光温室最佳朝向为南偏西10°。【结论】提出了日光温室建造最佳朝向仿真计算的方法，并通过实测及模拟的方法进行验证，为我国日光温室科学建造提供理论参考依据。
