武汉市10种优势园林植物固碳释氧能力研究

摘要

Carbon fixation and oxygen release capabilities of 10 dominant garden plants in Wuhan city were tested. The results show that evergreen plants and shrubs had more higher photosynthetic rate than deciduous plants and trees. Respectively, and the former had the same amount of carbon fixation and oxygen release per unit area as the latter. Among 10 species, as far as the total quantity of carbon fixation and oxygen release of individuals was concerned, Koelreuteria paniculate ,Platanushispanica and Cinnamomum camphora were on top 3, Ligustrum lucid-um, Photinia serrulata and Lagerstroemia indica ranked the last 3, deciduous plants and trees had a much bigger than evergreen plants and shrubs, respectively.%研究了武汉市10种优势园林植物的固碳释氧能力,结果表明:灌木的光合速率和单位面积固碳释氧量高于乔木,常绿植物的光合速率和单位面积固碳释氧量高于落叶植物；植物整株固碳释氧量以乔木和落叶植物分别高于灌木和常绿植物；供试植物中栾树、悬铃木和樟树的整株固碳释氧能力居前3位,女贞、石楠和紫薇居后3位.
