Assessment of Carbon Sequestration Capacity of Plants Common in Urban Parks
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.
