| 摘要: |
| 广泛的屋顶绿化是改善城市生态环境的重要举措。为探求中国高度城市化地区屋顶绿化建设推广的可行途径，综述了国外先进国家的屋顶绿化建设历程以及针对既有建筑的拓展型屋顶绿化的建设难点，并以中国屋顶绿化发展较早的上海为例，对其中心城区（即上海市外环线以内的区域，总面积约667.80km2）既有建筑的屋顶绿化进行了适建性评估。国外屋顶绿化建设领先的国家大多经历了从鼓励到强制、从新建建筑到既有建筑的历程；针对既有建筑的拓展型屋顶绿化的建设更具技术挑战性，必须进行构造创新、基质优化、植物精选和成本控制；上海已率先发布屋顶绿化建设的强制性政策，相关技术研发已有相当基础，但推广建设类型仍有局限，拓展型屋顶绿化极具建设潜力。 |

| Abstract: |
| Extensive green roofs help improve urban environment. To explore the feasible ways to promote roof greening in highly urbanized areas in China, this paper has summarized the course of green roof construction in advanced foreign countries and the difficulties in extensive green roof construction on existing buildings. It has takes Shanghai, a forerunner of roof greening in China, as an example and carried out suitability assessment of roof greening on existing buildings in the city’s central urban area (districts within the Outer Ring Road in Shanghai, with a total area of about 667.80km2). Most of the foreign countries advanced in green roof construction have gone through the development pattern from encouragement to coercion and from new buildings to existing ones. Construction of extensive green roofs on existing buildings is more challenging technically. Structural innovation, substrate optimization, plant selection and cost control are required. Shanghai has taken the lead in issuing mandatory policies on roof greening. Related techniques have been developed, but there are still limitations in construction types. The construction of extensive green roof has great potential in the city. |
