屋顶绿化研究进展

城市屋顶绿化是一种改善城市生态环境以及城市低碳的途径, 已经成为近年来我国提高城市绿量和建设低碳城市的重要趋势之一。国内屋顶绿化起步比较晚, 对其生态、隔热节能等方面的定量研究较少, 而国外特别是发达国, 对屋顶绿化的研究比较全面和深入。文中介绍屋顶绿化的定义及其分类, 综述屋顶植物抗性、屋顶植物筛选以及屋顶绿化在生态和隔热节能方面的国内外研究进展, 提出未来屋顶绿化研究的趋势, 以期为我国屋顶绿化研究和推广提供参考。

Study Progress of Rooftop Greening

Urban rooftop greening, as a approach to realizing low-carbon and improving the urban ecological environment, has become one of important trend in China to increase green quantity and construct low-carbon cities in recent years. Studies on rooftop greening started late in China and there are few reports on the quantitative study on ecological effect, heat insulation and energy performance of green roof. But the developed countries have carried out complete and in-depth study in this field. The definition and classification of rooftop greening were described in this paper. The resistance research of roof plants and their selection as well as the role of rooftop greening in ecological effect and heat insulation & energy performance at home and abroad were briefly reviewed. Then,the direction of future research on green roofs was also proposed with the expectation to provide references for the research and promotion of rooftop greening.
