摘　　要：介绍了覆土屋面蒸发冷却效果的计算方法 ,分析了土壤表面的热平衡 ,比较了普通屋面与覆土屋面外表面的温度波动 ,传导得热的差异和各种土壤的覆土屋面的传导得热量的变化。Describes the calculation method of evaporative cooling effects of earth covered roofs, analyses the heat balance and water mass balance of the roof surface, compares the surface temperature, conduction heat gains of the roof to those of a conventionally insulated roof, and provides maps of the evaporative cooling effects using the weather data of 66 cities in Japan.
