摘　　要：以太原市常见34种园林绿化植物为研究对象,通过测定净光合速率日变化,对其固碳释氧、降温增湿能力进行分析研究。结果表明,34种太原市常见绿化植物秋季的净光合速率日变化曲线多呈单峰型、少双峰型;单位叶面积固碳释氧能力分析表明,乔木、小乔木、地被、藤本单位叶面积固碳释氧能力分3级,灌木、绿篱灌木分2级,固碳释氧能力强的乔木有臭椿,小乔木有卫矛,灌木有月季,地被有苜蓿,藤本有金银花;单位叶面积降温增湿能力分析表明,乔木、灌木、绿篱灌木、地被分为2级,藤本和小乔木分为3级,降温增湿能力强的乔木有臭椿,小乔木有卫矛,地被有苜蓿、萱草、麦冬,藤本有山荞麦。In this paper, 34 common landscaping plants were studied in Taiyuan city. The net photosynthetic rate of tested plants were observed. Furthermore,the level of carbon fixation, oxygen production, temperature decrease and humidity increase were also evaluated. The results show that the diurnal change curve of net photosynthesis rates of 34 common landscaping plants in Taiyuan city has one peak, little two peaks. According to cluster analysis results, the carbon fixation and oxygen release capabilities per unit leaf area of arbors, small trees, groundcover plants, vines are divided into three levels, shrubs and hedge shrubs are divided into two levels. For daily carbon storage and oxygen release capabilities, the higher arbor is Ailanthus altissima, the higher small arbor is Euonymus bungeanus,the higher shrubs is Rosa chinensis Jacq, the higher groundcover is Medicago sativa Linn, the higher vine is Lonicera japonica Thunb.Temperature decrease and humidity increase capabilities per unit leaf area of arbors, shrubs, hedge bush, groundcover plants are divided into two levels, vines and small trees are divided into three levels. For daily temperature decrease and humidity increase capabilities, the higher arbor is Ailanthus altissima, the higher small arbor is Euonymus bungeanus, the higher groundcover are Medicago sativa Linn,Hemerocallis fulva and Liriope minor, the higher vine is Polygvnum aubertii.
