摘要 以长沙湘江新区交通枢纽中心屋顶绿化工程为例,介绍了天泉生态屋顶绿化专利技术的应用情况。该技术以无土生态基质和耐旱耐贫瘠植物为载体,将防渗、隔离防根、保水、轻型基质、植被等合为一体应用于城市屋顶绿化。实践表明:该技术可增加储水量36~50 L/m2,可使建筑内部平均降温2~3℃,同时节约空调耗电量20%~40%,对城市水资源的减流、削峰、再利用效果显著,在"海绵城市"建设中具有较好的应用前景。 Taking the roof greening project of the traffic hub in Changsha Xiangjiang New District as an example, introduced the application situation of Tianquan ecological roof green patent technology. The technology took the non-soil ecological substrate and the drought tolerant plant as the carrier, applied prevent leakage, anti-root isolation, water retention, light substrate, vegetation and so on as one to the urban roof greening. Practice showed that the technology can increase the storage capacity 36~50 L/m2, can make the interior of the building an average temperature drop 2~3℃, save the power consumption of air conditioner is 20%~40% at the same time, have the significant effect on the reduction of the urban water resources, peak shaving, and recycling, there is a good application prospects in the construction of "sponge city".
