郑州市15种常见园林树种固碳释氧能力分析研究
Crbon Fixation and Oxygen Release of 15 Common Landscape Trees in Zhengzhou
摘要
Abstract
In order to understand the benefits of landscape tree species to atmospheric environment,and to provide references for species selection and arrangement in the municipal ecological engineering system,the capabilities of carbon fixation and oxygen release of 15 common native greening species in Zhengzhou were investigated.The values of carbon fixation and oxygen release of an individual tree among 15 species ranged from 21.90 to 779.17 and 16.59-583.03 g · d-1,respectively.The values of photosynthetic rate were arbor species:6.16,shrub species..7.36,evergreen species..6.15,and deciduous species:6.64 μmol · m-2 ·s-1.The values of carbon fixation of arbor,shrub,evergreen,and deciduous species per plant were 386.45,110.55,216.58,and 339.56 g · d-1,respectively,while the values of oxygen release of these species were 283.55,89.83,148.50,and 247.73 g · d-1,respectively.Carbon fixation and oxygen release per unit area of shrubs were higher than those of arbors,and of evergreen species were were higher than those of deciduous species.It was concluded that plant species that demonstrated higher capability of carbon and oxygen release were Koelreuteria paniculata,Magnolia grandi flora and Platanus aceri folia,while Lagerstroemia indica,Prunus cerasifera and Amygdalus persica showed weaker capability to fix carbon and release oxygen.关键词
