    摘要:全球气候变化和快速城市化导致的城市生态环境急剧退化问题已经成为影响区域可持续发展的重要因素,而低碳城市是应对这一问题的重要对策之一。作为低碳城市建设的重要内容,低碳园林开始受到了城市管理者和规划人员的重视。但目前低碳园林仅处于概念层面,缺乏具体的实施途径。在全球气候变化和快速城市化对城市人居环境的影响、低碳园林概念及其与低碳城市关系辨析的基础上,从生态学角度探讨了低碳园林的发展策略。提出了增加城市绿量、改善景观布局、选育应用功能性植物、建设近自然园林、综合利用水资源及引导居民参与园林建设等低碳园林规划建设的生态学途径,以期为低碳园林和低碳城市的规划建设提供实施依据。

    Abstract:The sharp degradation of urban ecological environment resulted from global climate change and rapid urbanization has become an important affecting factor of regional sustainable development. Low-carbon city is a considerable countermeasure to solve this problem. Being an important part of low-carbon city construction, low-carbon urban landscape has attracted increasing interests from city managers and planners. To date, however, low-carbon urban landscape still stays at the conceptual level, and lacks for specific implementation approaches. Based on the influence of global climate change and rapid urbanization to the urban living environment, the concept and the relationship between low-carbon urban landscape and low-carbon city, the strategy of the low-carbon urban landscape development was discussed from an ecological perspective, and the strategies of low-carbon urban landscape planning and construction were proposed, in order to provide practical reference for planning and construction of low-carbon city and low-carbon urban landscape. These strategies included increasing green quantity, improving the landscape pattern, breeding and applying functional plant, constructing semi-natural landscape, synthesis utilization of water resources and constructing participatory urban landscape, etc.
