摘　　要：【目的】温室屋面为两个坡面、一个拱形面共同组成,风雪载荷较为复杂。对新疆北部地区日光温室风雪载荷进行计算分析,为新疆设施农业进行温室结构设计提供参考和实践依据。【方法】就新疆西山农场日光温室的风雪载荷展开分段式分析计算。【结果】所得风雪载荷值Wk=0.446 7 KN/m2、S=0.86 KN/m2,在《建筑结构荷载规范》(QB50009-2012)雪载值和风载值的范围内,并通过了生产实践检验。【结论】分段式方法分析计算温室复合屋面风雪载荷准确可行。[ Objective] Under the background of facility agriculture development in Xinjiang, the varietyof load needs to be calculated in the greenhouse structure design, among them, the wind - snow load is themost important, because the greenhouse roof is made of two slopes and an arch surface. [ Method ] The wind -snow load was calculated and analyzed in designing sunlight greenhouses by stages in Xishan Farm in Xinjiangin this paper. [ Result] The results of wind - snow load （ wk = 0. 446,7KN/m2, S = 0.86 KN/m2 ） accordedwith Load Criterion of Building Structures （ QBS0009 - 2012）, which proved feasible in practice. [ Condu-sion] It proved that the calculation of the wind -snow load of the greenhouse composite roofs by stages was ac-curate and feasible ,which offered practical basis and references for sunlight greenhouse design.
