[Objective] The purpose of the research was to provide the theory pursuant for the sunlight greenhouses optimization design in Tacheng area, so as to improve the comprehensive performance of Xinjiang sunlight greenhouses. [ Method] Two newly constructed solar greenhouses in 2010 in Tacheng suburb that has the regional features of northern Xinjiang were selected as the representative. Through the testing results of the two greenhouses environment parameters, the influence of greenhouses height and span on the sunlight greenhouses climate environment (the environment of crop cultivation) in high latitudes and cold climate circumstances was analyzed. [ Result ] In the same condition, the main factor affecting greenhouses light transmittance is the volume and span of the greenhouses. [ Conclusion ] The main measures of improving greenhouses light transmittance are to increase the greenhouse span and keep a reasonable depth - span ratio.%[目的]为塔城地区日光温室的优化设计提供理论依据,从而提高北疆日光温室的综合性能.[方法]选取具备代表北疆地域特点的塔城市郊2010年新建的两座日光温室为代表,通过对这两座温室环境参数的测试,分析在地理纬度大、气候特征寒冷的情况下日光温室高度与跨度对日光温室小气候环境(作物栽培环境)的影响.[结果]在相同长度的条件下,温室容积和跨度是影响温室保温性及透光率的主要因子.[结论]增加温室跨度,保持合理的高跨比是提高温室保温性及透光率的主要因素.考虑到建造的经济性,高跨比较低的日光温室要优于较高的日光温室.
