摘要
通过测定叶面积指数、光合速率及蒸腾速率,比较分析了深圳市12种垂直绿化植物释氧固碳、吸热降温增湿效应,并量化评价了这些植物的生态学效应.结果表明,桂叶老鸦嘴Thunbergia laurifolia的单位绿化面积释氧量为65.48 g.m-2d-1,固碳量为90.07 g.m-2d-1,使其周围1000 m3空气降温达到2.14℃,相对湿度增加2.60%,而凌霄Campsis grandiflora的上述指标分别只有2.78 g.m-2d-1、3.83 g.m-2d-1、0.16℃及0.16%.
The capacities of oxygen release, transpired water release, and absorbed caloric were calculated by measuring leaf area indices, photosynthetic rates, and transpiration rates of the twelve species for vertical greening in Shenzhen. The ecological benefits were also evaluated quantitatively. The results showed that Thunbergia laurifolia released 65.48g·m^-2 d^-1 O2 and absorbed 90. 07 g·m^-2 d^-1 CO2 in a day, and it reduced air temperature by 2. 14 ℃ per 1 000 m^3 and increased air humidity by 2. 60% ; comparatively, the figures for Campsis grandiflora were only 2. 78 g·m^-2 d^-1 3.83 g·m^-2 d^-1 0. 16℃ and 0. 16%, respectively.
