城市绿化植物的固碳释氧效应

Effect of Carbon Fixation and Oxygen Release about Urban Greening Plants

以哈尔滨市常见的8种树种糖槭、榆树、白桦、山桃稠李、金银忍冬、连翘、紫丁香、榆叶梅为研究材料,利用LCA-4型红外气体分析系统进行一个生长季的观测;以观测数据为基础,对8种树种的固碳释氧量进行了比较。结果证明,在整个生长季中,8个树种的固碳释氧量由高到低排列为榆树、糖槭、紫丁香、白桦、榆叶梅、连翘、金银忍冬、山桃稠李。同时对各树种整个生长季固碳释氧量的趋势进行了分析,对树种的配置提出建议。

Eight common tree species in Harbin City were used as research materials, such as Acer saccharum, Ulmus pumila, Betula platyphylla, Prunus maackii, Lonicera maackii （Rupr.） Maxim, Forsythia mandshurica, Syringa oblate, and Prunus triloba. An observation on the carbon fixation and oxygen release of these tree species was made with LCA - 4 infrared gas analytical system during a whole growing season. Based on the observations, the amounts of carbon fixation and oxygen release for the eight trees species were compared. During the whole growing reason, the amounts of carbon fixation and oxygen release were sequenced from high to low, namely, Ulmus pumila, Acer saccharum, Syringa oblata, Betula platyphylla. , Prunus triloba, Forsythis suspensa, Lonicera maackii （Rupr.） Maxim, Prunus maackii. Meanwhile, the trends of carbon fixation and oxygen release of each tree species in the whole growing season were analyzed, and some proposals about tree species collocation were also given.
