摘　　要：为探求越冬期间日光温室内部温度变化特性,对离石区日光温室内部空气温度、墙体温度、室内地温、室外气温等进行了整个越冬期的跟踪观测。结果表明,晴天日光温室内部空气温度的日变化呈单峰曲线,阴天时日变化曲线没有呈现明显的单峰形式;白天墙体和室内土壤都处于吸热的状态,是吸热体,夜间墙体和土壤都处于放热状态,是放热体。室内空气温度变化在白天和夜间,在垂向、横向、纵向都呈现出规律性变化,原因是维护结构与室内存在温度差,在不同时段吸放热量所致,并且日照的时间长短也影响室内气温的分布。越冬期内日光温室增温效果良好,并且室内气温与室外气温具有较好的相关关系,可用室外气温预测室内气温。In order to study the temperature change characteristics inside the greenhouse during the winter,the tracking tests were carried out in winter,including the air temperature inside and outside the greenhouse,the temperature of the wall,the ground temperature inside the greenhouse and so on.The result shows that daily variation of the temperature inside the greenhouse takes the form of unimodal curve on a sunny day,on the contrary,it does not show obvious unimodal form on a cloudy day.The wall and the soil inside the greenhouse are in heat absorption shape in the daytime,and they are heat receiver;they are in heat release shape in the night,and they are heat releaser.The temperature inside the greenhouse carries out regular variations in the transverse,longitudinal and vertical directions both in the day and night.The reason for this phenomenon is that there is temperature difference between exterior protecting construction and the air inside,and the exterior protecting construction absorbs and releases heat during different period of the day.Sunshine duration can also influence the air temperature distribution inside.The effect of temperature increase of the greenhouse is obvious and there is a good relationship between the air temperature inside and outside,iudicating that air temperature outside can be used to forecast the air temperature inside.
