为了给寿光日光温室生产的可持续发展提供科学的气象理论依据，对寿光市1959—2014年冬季气温、光照、风速、天气状况等影响日光温室生产的几个主要外部气象因子进行分析。研究发现：寿光冬季气温呈显著上升趋势，低温日数减少，表明寿光冬季寒冷程度减弱，异常暖冬月和暖冬年的频繁发生，为寿光日光温室的发展提供了充足的热量资源。冬季风速呈显著减小趋势，温室表面换热系数减小，减少了温室内外的热量交换和温室内热量的散失。寿光冬季日照时数和晴天日数减少、阴天和大雾日数的增加是发展日光温室的不利因素，但降雪日数的减少和温度的升高在一定程度上弥补了日照时数减少对日光温室产生的不利影响。综合分析，寿光冬季发展日光温室的气象条件较好。
為瞭給壽光日光溫室生產的可持續髮展提供科學的氣象理論依據，對壽光市1959—2014年鼕季氣溫、光照、風速、天氣狀況等影響日光溫室生產的幾箇主要外部氣象因子進行分析。研究髮現：壽光鼕季氣溫呈顯著上升趨勢，低溫日數減少，錶明壽光鼕季寒冷程度減弱，異常暖鼕月和暖鼕年的頻繁髮生，為壽光日光溫室的髮展提供瞭充足的熱量資源。鼕季風速呈顯著減小趨勢，溫室錶麵換熱繫數減小，減少瞭溫室內外的熱量交換和溫室內熱量的散失。壽光鼕季日照時數和晴天日數減少、陰天和大霧日數的增加是髮展日光溫室的不利因素，但降雪日數的減少和溫度的升高在一定程度上瀰補瞭日照時數減少對日光溫室產生的不利影響。綜閤分析，壽光鼕季髮展日光溫室的氣象條件較好。

The paper aims to provide meteorological theory basis for the sustainable development of the production in solar greenhouse in Shouguang City. Through statistic analysis of several external meteorological factors such as the winter air temperature, sunshine duration, wind speed, weather conditions and so on that influenced the solar greenhouse production in Shouguang City from 1959 to 2014, it was found that the air temperature was obviously on an increasing trend, and low temperature days were decreasing. It indicated that the cold degree was reducing in winter in Shouguang City, and the abnormal mild months and the years with mild winter frequently occurred, which provided sufficient heat resources for the development of solar greenhouse. The wind speed in winter was on a decreasing trend, which reduced the heat transfer coefficient on the surface of greenhouse and reduced the loss of heat in the greenhouse when the heat inside and outside exchanged. The decrease of sunshine duration and sunny days in winter in Shouguang City and the increase of cloudy days and foggy days were adverse factors for the development of solar greenhouse production, but the decrease of snowing days and the increase of temperature made up the diverse effect caused by the decrease of sunshine duration to solar greenhouse production. By comprehensive analysis, the weather conditions for developing the solar greenhouse production in winter in Shouguang City were relatively good.
