摘　　要：城市里大量的不透水面引发绿地空间严重缩水、热岛效应加剧、城市雨洪频发等一系列严重的城市环境问题。解决人口密度大、绿化用地少与高质量实现扩绿增绿、实现城市居民对美好生活向往的矛盾,成为城市生态建设和环境提升的核心难题,开展路面、屋面、墙面及桥柱等城市特殊生境绿化成为城市高质量发展和城市品质提升的关键抓手。以上海为例,总结了近20年来城市特殊生境绿化的研究进展,围绕植物、介质、模块和管护四要素,从生境的特殊性、适生植物种质创新和定向筛选、生境重建、一体化技术、低维护管理及功能评价等方面取得了系列理论积淀和技术创新,实践了有限空间的持续生长理念,形成完整的特殊生境绿化技术体系,为公园城市建设发挥重要支撑作用。A large number of impervious surfaces in cities have led to a series of serious urban environmental problems,such as serious shrinkage of green space,aggravated heat island effect,and frequent urban rain floods.Solving the contradiction between high population density,low green space and high-quality expanded greening,and the realization of urban residents’yearning for a better life,has become the core problem of urban ecological construction and environmental improvement,and the development of special urban habitats such as roofs,walls and bridge pillars greening has become the key to urban high-quality development and urban quality improvement.Taking Shanghai as an example,this article summarizes the research progress of technological achievements in the greening of special habitats in the past 20 years,focusing on the four elements of plants,media,modules,and management.It has made a series of theoretical accumulations and technological innovations in habitat particularity,suitable plant germplasm innovation and targeted screening,habitat reconstruction,integrated technology,low maintenance management,and functional evaluation.The results have practiced the concept of continuous growth in limited space,formed a complete technical system for special habitat greening,and played an important leading role on urban greening.
