试验采用PC-2 R型热通量记录仪对酒泉肃州区非耕地日光温室的山墙及栽培基质热通量进行实时监测,并对温室山墙及栽培基质热通量变化特性进行了分析.结果表明：温室东西山墙单位面积吸热量平均值分别为1.41 MJ/m2和1.67 MJ/m2,单位面积墙体放热量平均值为0.34 MJ/m2和0.63 MJ/m2；天气状况只影响山墙热通量值的大小,对其热通量达到最大值的时刻无影响；白天栽培基质表层平均吸热量为0.59 MJ/m2,夜间栽培基质表层平均放热量为0.17 MJ/m2；随栽培基质深度的增加,热通量变化幅度逐渐降低,蓄热的时间依次延迟；15 cm以下基质热通量全天均为负值,晴天与阴天吸放热差异不明显；晴天夜间山墙单位面积放热量高于基质,阴天则小于基质.

In this research,PC-2R type heat flux recorder was employed to actualize a real time monito-ring of heat flux of gable and culture medium in greenhouse of non cultivated land in Suzhou District of Ji-uquan,and the characteristics of heat flux of gable and cultivation were analyzed.The result indicated that, the average value of unit area of heat absorption of east gable and west gable were 1.41 MJ/m2 and 1.67 MJ/m2 ,respectively,and the average value of unit area of heat releases of gables were 0.34 MJ/m2 and 0.63 MJ/m2 .Weather conditions only affected the heat flux values of gables,but had no influence on the maximum moment of heat flux.The average heat absorption on the surface of culture medium in the daytime was 0.59 MJ/m2 ,and the average heat release on the surface of culture medium in the night was 0.17 MJ/m2 .With the increasing of substrate depth,the amplitude of heat flux variation decreased gradual-ly,and the time of accumulation of heat delayed in turn.The heat flux under 1 5 cm of culture medium was negative all day,and the difference between sunny day and cloudy day was not significant.At the night of sunny day,the average value of unit area of heat releases of gables was higher than that in the culture medi-um,however,in the night of cloudy day,it was lower.
