摘　　要：为研究高海拔地区极端天气情况下温室内热环境的影响及变化规律,以乌恰县戈壁石砌后墙番茄种植日光温室为例,在温室内布置相应的温度传感器进行数据采集,获取晴好天气下日光温室内温度环境分布情况。结果表明:全天20℃以上温度时长约8小时,30℃以上温度时间段为13:30~17:30,温度高于30℃时间为4小时左右,此段时间内温度超出番茄适宜生长温度,不利于番茄的快速生长和果实发育成熟,此时应加强温室通风,及时降低温度。23:00~10:30期间,温度基本降至15℃及以下,不利于番茄正常生长,应提前做好温室保温措施,减少温室内热量散失。In order to study the influence and change rules of the internal thermal environment in the green-house under extreme weather conditions in the high altitude area, taking the Gobi stone back wall tomato growing solar greenhouse in Wuqia County as an example, the corresponding temperature sensor is arranged in the greenhouse for data acquisition, and the temperature environment distribution is obtained in the solar greenhouse in sunny day. The results indicate that the temperature above 20˚C lasts up to 8 hours. The temperature above 30˚C lasts for about 4 hours from 13:30 to 17:30. The temperature exceeds the suitable growth temperature of tomato during this period, which is not conducive to the rapid growth and fruit development of tomato. At this time, ventilation in the greenhouse should be strengthened and the temperature should be lowered timely. From 23:00 to 10:30, the temperature basically drops to 15˚C or lower, which is not conducive to the normal growth of tomatoes. Take heat-preservation measures in advance to reduce heat loss in the greenhouse.
