摘　　要：针对浅层地能低品位的特点,在中国农业科学院Venlo型试验温室内设计建造了一套地源热泵与地板散热方式相结合的供暖系统,并对加热效果进行了试验,结果表明:温室内垂直方向的气温随着高度的增加而下降,水平方向气温分布均匀,温度分布有利于植物的生长。整套地源热泵系统的实际制热系数COP值达到3.14,与燃煤锅炉相比节能36.3%,节能效果明显。According to the characteristics of superficial geothermal energy, ground-source heat pump（GSHP） and floor heating were used for the greenhouse heating in winter. The ground-source heat pump greenhouse heating system was installed in a Venlotype test greenhouse of the Chinese Academy of Agricultural Sciences. The results showed that the temperature of greenhouse in the vertical direction decreased with the increase of height, and the temperature in the horizontal direction was well distributed and helpful to plant growth. The actual heating coefficient of performance（COP） of the GSHP was 3.14. The experimental greenhouse heated by GSHP saved energy by 36.3%, compared with that in the greenhouse heated by coal fuel.
