Abstract:: Taking two solar-greenhouses which with typical brick-wall and Gobi stone walls in Gobi Region of South Xinjiang as research object,winter production environment and wall heat flux were studied on two solar-greenhouses,in order to provide theoretical basis to manegement,maitainance and new construction of solar-greenhouse in Gobi Region of South Xinjiang.The results showed that the greenhouse of Gobi stone wall warmed up faster in the sunny day，and without ventilation，the inner highest temperature could be 8℃ higher than it in brick wall.Meanwhile the test of wall heat flow showed such two kinds of wall shared a similar heat storage capacity in the day time while the exothermic effect of Gobi stone wall was better in the night.However，due to the reason of structure differences and bad management，both the air and soil temperature of Gobi Stone wall greenhouse were significantly lower than brick walls greenhouse，even below 0℃ in the night.It was clear that the greenhouse insulation performance and management levels should be further improved.
