摘　　要：在夏季,一般建筑顶层的室内热环境最差。种植屋面降低了屋面的太阳辐射,对改善顶层室内的舒适性有着积极的作用。选择长沙市某商业综合楼的屋面,将其划分为几种不同土壤厚度和不同种植植物的实验模块,在相同的室外环境作用下,连续测试各模块的内表面温度、土壤底部温度等并进行对比分析。结果表明:当屋面自身具有较好的隔热性能时,再进行屋面种植,效果不太明显。In the summer, the indoor thermal environment of the building top is generally worst. Planting roof reducing the solar radiation to improve the comfort of the top floor has a positive effect. A complex building commercial roofing is chosen in Changsha City, which is divided into experimental modules with different soil depth and different plants. These modules are tested and compared continuously on inside surface temperature and soil bottom temperature the effect of the roof planting is not obvious when under the same outdoor environment. The results show that the roof has good thermal insulation performance.
