摘要
城市公园植物群落的固碳作用是缓解城市环境问题的有效途径之一。量化植物在光合作用中固定的二氧化碳,估算出植物群落固碳效益,可使设计师对方案进行调整。本文以天津公园植物群落为研究对象,选取公园内12个相对典型的植物群落,利用NTBC估算城市公园植物群落的年固碳效益,归纳植物群落的固碳能力与不同影响因素之间的关系。探讨城市公园内植物群落的设计优化策略,既要考虑植物的固碳能力和生态效益,也要平衡植物群落的其他多种功能,营造和谐的城市生态环境。
The carbon sequestration of plant communities in urban parks is one of the effective ways to alleviate urban environmental situations.Quantifying the carbon dioxide that plants fix in photosynthesis and estimating the carbon sequestration benefits of plant communities can allow designers to adjust the projects.Taking theplant communities in Tianjin park as the research object,selecting 12 typical plant communities in the park,and estimate the annual carbon sequestration efficiency of the urban park plant community by NTBC.Summarize the relation between the carbon sequestration ability of plant communities and different influencing factors.Finally,to explore the design optimization strategy of plant communities in urban parks,it is necessary to consider the carbon sequestration capacity and ecological benefits of plants,as well as balance other functions of plant communities and create a harmonious urban ecological environment.
