Abstract: Six species of climbing plants in Guangzhou, including Parthenocissus dalzielii, Bougainvillea spectabilis, Quisqualis indica, Pyrostegia venusta, Wisteria sinensis, Lonicera japonica, were studied to appraise their effects on decreasing temperature and increasing humidity by taking an observation of the carbon dioxide absorbing capacity, oxygen producing. Results showed that B. spectabilis had the highest capability of carbon dioxide absorbing and oxygen producing, and P. dalzielii had the highest level of humidity increase capability. Therefore, it was suggested that P. dalzielii, Q. indica and B. spectabilis should be the first choice in the landscape plants configuration for the city road.

Key words: climbing plant, carbon sequestration and oxygen release, cooling and humidification

摘要： 对广州市常用的6种攀援植物进行叶面积指数、光合速率和蒸腾速率测定，比较分析其释氧固碳和降温增湿效益。结果表明，簕杜鹃Bougainvillea spectabilis单位绿地面积固碳释氧量最大，降温效果最明显；异叶爬墙虎Parthenocissus dalzielii增湿效果最好。在园林绿化中，城市立体绿化攀援植物可首选异叶爬墙虎、使君子Quisqualis indica和簕杜鹃。
