摘　　要：选择适应屋顶严酷环境条件的绿化植物是屋顶绿化能否成功的关键。以铺地锦竹草(Callisia repens)、佛甲草(Sedumlineare)和细叶结缕草(Zoysia tenuifolia)作为试验材料,在广州真实屋顶环境条件下开展适应性评价试验,并通过测定屋顶绿化试验区房屋各部位的温度变化分析屋顶绿化的降温效果。研究结果表明,铺地锦竹草生长迅速,建植2个月盖度达78.75%,连续6个月无养护也正常生长,表现出良好的适应性,且盖度、均一性和颜色均优于佛甲草和细叶结缕草;佛甲草不耐高温,夏季生长十分缓慢,建植2个月盖度仅22.50%;细叶结缕草建植2个月盖度达77.50%,但无养护6个月后盖度仅存7.50%,不耐长时间干旱。高温季节屋顶绿化可降低屋顶楼面温度9.78℃,天花板温度2.73℃,室内温度0.87℃。综上,在华南地区屋顶绿化当首推铺地锦竹草,佛甲草和细叶结缕草不适合使用。研究结果将为华南地区屋顶绿化提供参考。The key to the success of roof greening is to select greening plants adapted to the harsh environmental conditions on the roof.In this study,callisia repens,Sedum lineare and Zoysia tenuifolia were used as experiment materials to carry out adaptability evaluation experiment under the real roof environmental conditions in Guangzhou,and the cooling effect of roof greening was analyzed by measuring the temperature changes in different locations of the roof greening experiment areas of the building.The results showed that callisia repens grew rapidly,with a coverage of 78.75%after 2 months of planting and displayed good adaptability with normal growth condition without maintenance for 6 months and better performances than Sedum lineare and Zoysia tenuifolia in terms of coverage,uniformity and color.Sedum lineare grew very slowly in summer due to its poor resistance to high temperature,with a coverage of only 22.50%after 2 months of planting.Zoysia tenuifolia reached coverage of 77.50%after 2 months of planting,but only 7.50%of its coverage remained after 6 months without maintenance,indicating it was not tolerant to long period drought.In high temperature season,roof greening can reduce the roof surface temperature by 9.78℃,ceiling temperature by 2.73℃and indoor temperature by 0.87℃.To sum up,for roof greening in Southern China region,callisia repens was recommended first,while Sedum lineare and Zoysia tenuifolia could not be suitable for use.The results will provide reference for roof greening in Southern China region.
