摘　　要：采用对比测试方法对轻型生态种植模块的隔热特性进行了实验研究。设置了4种测试模块,即轻型种植土加湿模块、干模块、佛甲草种植模块及蓄水模块。为了比较其隔热特性,采用额定功率为1000 W的卤素灯模拟太阳辐射,在相同实验环境下进行测试分析。结果表明,佛甲草种植模块的表面温度、底面温度及导热热流均低于其它对比模块,佛甲草种植模块具有较好的隔热效果。In this paper the thermal insulation properties of light ecological planting module is studied by contrast experi- ment. In the experlment, in order to compare the thermal insulation properties for different modules,four kinds of modules,i.e, light plating earth humidifying module, dry module, sedum lineare planted module and water storage module, are established in the same testing environment,and their thermal insulation properties are tested and compared. In addition,the solar radiation is simulated under the halogen lamp with 1000 W rated power. The testing results show that the. surfaee temperature,bottom temperature and thermal conductivity of heat flow of sedum lineare planted module are lower than other modules,it has better thermal insulation properties.
