太原市主要园林植物春季固碳释氧和降温增湿效应

Carbon Fixation and Oxygen Production and Cooling and Humidifying Effect of the Main Landscaping Plants in Spring in Taiyuan City

为了探究太原市园林植物春季固碳释氧和降温增湿效应,选取了6类34种园林植物,通过定量计算,对其固碳释氧和降温增湿能力进行了初步评估和分类评价。结果表明,单位叶面积固碳释氧效应最强的为乔木的泡桐、小乔木的卫矛、灌木的珍珠梅、绿篱灌木的小叶女贞、地被的苜蓿、藤本的山荞麦;单位叶面积降温增湿效应最强的为乔木的泡桐、小乔木的卫矛、灌木的榆叶梅、绿篱灌木的小叶女贞、地被的苜蓿、藤本的山荞麦。对园林植物的固碳释氧、降温增湿能力进行分类评价,共分为高、中、低3个等级,分为同等级的植物固碳释氧、降温增湿效应相近,在园林配置中可互换。结果可为城市园林绿化中植物的选择提供科学依据。

To quantitatively explore the effect of carbon fixation and oxygen production and cooling and humidifying for landscapingplants in spring, the paper selected thirty-four main landscaping plants in Taiyuan, combined with calculation and cluster analysis, thecapacity of carbon fixation, oxygen production, cooling and humidifying were estimated and classified. The results showed that thecapacity of carbon fixation and oxygen production per unit of leaf area, the higher arbor is Paulownia tomentosa, the higher dungrungawas Euonymus bungeanus, the higher shrubs was Sorbaria kirilowii, the higher hedge shrubs was Ligustrum quihoui Carr., the higherground covers was Medicago sativa Linn., the higher vines was Polygvnum aubertii. The capacity of cooling and humidification per unit ofleaf area, the higher arbor was Paulownia tomentosa, the higher dungrunga was Euonymus bungeanus, the higher shrubs was Amygdalustriloba, the higher hedge shrubs was Ligustrum quihoui Carr., the higher ground covers was Medicago sativa Linn., the higher vines wasPolygvnum aubertii. The abilities of carbon sequestration, oxygen release, cooling and humidification of garden plants were classified andevaluated. The same kind of plants had similar capacity of carbon fixation and oxygen production, cooling and humidifying, could beexchanged in the landscaping configuration. The above results will providea scientific basis for the choosing plants in urban landscaping.
