Carbon fixation and oxygen release of landscaping trees along the Grand Canal in Yangzhou

Abstract: It is six years from the completion of the Grand Canal in Yangzhou City .How about its ecological effects ? Carbon fixation and oxygen release of landscaping plants along the Grand Canal were studied from June to August of 2006 , and 19 typic plant species were chosen to determine with the aid of the LI-6400 portable photosynthesis system.The results showed that the 19 species were classified into three types according to their daily ability to fix carbon and release oxygen per unit area :those higher than 65 gm-2d-1 including Ligustrum quihoui , Robinia pseudoacacia and Salix babylonica ;those between 26 gm-2d-1 and 58 gm-2d-1 including Cinnamomum camphora , Citrus medica , Eriobotrya japonica , Ligustrum lucidum , Magnolia grandiflora , Viburnum awabuki , Ginkgo biloba , Prunus cerasifera , Sophora japonica , Amygdalus persica , Magnolia denudata , Nerium indicum , Forsythia viridissima , Jasminum nudiforum and Chimonanthus praecox ;and those lower than 8 gm-2d-1 , only Osmanthus fragnans .L .quihoui had highest daily ability to fix carbon (115.021 1 gm -2d-1)and release oxygen (83.638 0 gm-2d-1) .S .babylonica and A .persica , which are main species along the canal , have high ability to fix carbon and release oxygen , so it shows that the planting arrangement of the canal is ideal .[ Ch ,1 fig .4 tab .9 ref .]
