摘　　要：【目的】研究不同后屋面类型对日光温室温度和光照强度变化的影响,为日光温室结构选型提供理论依据。【方法】以后屋面为2和1 m和无后屋面三种不同结构类型的日光温室为研究对象,对宁夏南部山区温室建造成本和冬季寒冷时期的温度、光照变化进行比较。【结果】日光温室建造成本,温室1>温室2>温室3。保温性能,温室2>温室3>温室1。采光量,温室3>温室2>温室1。【结论】从温室建造成本、保温、采光来看温室3更经济节能。根据温室建造费用及温度、光照试验对比分析,温室3是更适合宁夏南部山区气候特点及经济发展水平的日光温室类型,适宜在该地区建造,该种类型温室在后期园区扩建及辐射推广中能够大幅降低建造成本。[ Objective ] To explore the effects of different roof types on the greenhouse temperature andlight intensity and provide a theoretical basis for the selection of structures of sunlight greenhouses. [ Method ]The three types of structure of roofs of solar greenhouses with 2m, lm and roofs without the back part wereused as the research object, and they were studied and compared through the data such as the constructioncost, temperatures in the winter time and the light changes in southern mountainous area in Ningxia. [ Re-suits] The construction cost： greenhouse type 1 〉 greenhouse type 2 〉 greenhouse type 3. Thermal insula-tion performance： greenhouse type 2 〉 greenhouse type 3 〉 greenhouse type 1. Lighting quantity： green-house type 3 〉 greenhouse type 2 〉 greenhouse type 1. [ Conclusion ] From the viewpoint of a greenhouseconstruction cost, thermal insulation and lighting, the type 3 greenhouse was more economical.Through theanalyses of the above factors, this type was more adaptable to the climate and economical development level insouthern Ningxia mountainous area; therefore it was suitable to be built in the place, thus reducing construc-tion cost greatly and saving money as well, if it would be promoted in the later expansion.
