摘要
为探究杭州市常见植物在四季生长过程中的固碳能力,以杭州西湖风景名胜区典型的 50 种植物为研究对象,结合便携式光合仪和植物冠层分析仪创新研究方法,分别测算植物四季的光合速率及叶面积,以评估其固碳能力.结果表明:广玉兰固碳能力最强,樟、三球悬铃木等较强,火棘、绣球、金丝桃较弱;乔木固碳能力强于灌木,常绿乔木固碳能力最强;不同季节植物固碳能力为:夏季>秋季>春季>冬季.因此,在植物群落设计时,应加强高固碳能力植物的应用,增加常绿乔木的比例,最大程度提升植物景观美学价值和生态效益.
Abstract
In order to investigate the carbon sequestration capacity of plants common in Hangzhou,the study selects 50 typical species of plants in the West Lake Scenic Area of Hangzhou to measure the photosynthetic rate and leaf area of plants in the four seasons using portable photosynthetic apparatus and plant canopy analyzer,and evaluates their carbon sequestration capacity.The results show that Magnolia grandiflora has the strongest capacity in carbon sequestration,followed by Cinnamomum camphora and Platanus orientalis,while Pyracantha fortuneana,Hydrangea macrophylla and H.monogynum have the weaker capacity.Trees have higher carbon sequestration capacity than shrubs,while the evergreen trees sequester the most carbon.Plants have different capacity in carbon sequestration in the four seasons,which is ranked as summer>autumn>spring>winter.It indicates that in the design of plant communities,more focus should be placed on the application of plants with higher carbon sequestration capacity,and the proportion of evergreen trees should be increased,so as to maximize the aesthetic and ecological benefits of plant landscape.
