| Abstract: | Objective] This paper provides basis for green space planning,colorful plants selection and the rational allocation of resources.Method] Li-6400 photosynthesis system was used to determinate the photosynthetic characteristics of five Aceraceae colorful plants in Shanghai area.Furthermore,the amounts of carbon fixation and oxygen release of these plants were studied.Result] The net photosynthetic rate and the amounts of carbon fixation and oxygen release of five colorful plants were different.The diurnal average photosynthetic rate and ability of carbon fixation and oxygen release per unit leaf area of Acer buergerianum,Acer palmatum and Acer palmatum ＇Atropurpureum＇were better,Acer cinnamomifolium and Acer truncatum displayed lesser.Conclusion] In terms of the whole plant,the order of daily carbon fixing and oxygen releasing capabilities was as follows：Acer cinnamomifolium,Acer buergerianum,Acer palmatum ＇Atropurpureum＇,Acer palmatum,Acer truncatum. |
