室内垂直绿化植物生态效益研究

摘要

Objective] To investigate the ability of vertical greening plants on improving indoor environment.[Method] The efficiency of carbon sequestration, oxygen release, cooling, humidification and dust-retention of 6 indoor vertical greening plant species ( including A.‘Sliver Queen’, E.aureaum‘Virens’, P.mandaianun‘Royal Queen’, A.Andraeanum, P.Tetraphylla, S.podophyllum‘While Butterfly’)was quanti-tatively measured and comprehensively evaluated.[ Result] The results suggested that all the vertical greening plants showed significantly im-provements on indoor environment quality, with various effects by different plants.E.aureaum‘Virens’ was the best plant species of carbon se-questration and oxygen release per unit of plant green area, which absorbed 5.48 g/CO2 and released 3.98 g O2 every daytime.While P.manda-ianun ‘Royal Queen’, released 581.34 g water vapor and absorbed 1 415.85 kJ heat every daytime per unit of green area, as well as reducing temperature of 0.12 ℃, was the best plant with cooling and humidification capabilities.A.andraeanum had the best capability of daily dust-reten-tion per unit of green area, which retained 0.010 0 g dust daily and 3.640 0 g annually.[Conclusion] The ranking of comprehensive ecological effect of the 6 vertical greening plants per unit of green area was A.‘Sliver Queen’, E.aureaum‘Virens’, P.mandaianun‘Royal Queen’, A. Andraeanum, P.Tetraphylla, S.podophyllum‘While Butterfly’.This study implies building vertical greening system should consider the integrat-ed ecological effect instead of purely landscape effect .%[目的]了解垂直绿化植物改善室内环境的能力。[方法]对绿萝、红钻、银皇后、紫边碧玉、白蝴蝶、红掌6种室内垂直绿化植物进行了固碳释氧、降温增湿和滞尘效益的定量分析及综合评价。[结果]垂直绿化植物对室内环境的改善效果显著，不同植物的生态指标效益不同。植物单位绿化面积固碳释氧效益以绿萝最佳，单位绿化面积日固碳量为5．48 g／（m2· d），单位绿化面积日释氧量为3．98 g／（m2· d）；降温增湿效益以红钻最佳，单位面积日增湿量为581．34 g／（m2· d），单位绿化面积日降温量1415．85 kJ／（m2· d），并可降低温度0．12℃；滞尘效益以红掌最佳，单位面积日滞尘量为0．0100 g／（m2· d），单位面积年滞尘量3．64 g／（m2· d）。[结论]6种植物单位绿化面积的综合效益从大到小依次为银皇后、绿萝、红钻、红掌、紫边碧玉、白蝴蝶。垂直绿化的建设不能只追求景观效果而忽略植物的生态价值，应多选择生态效益综合评价较好的植物，以较好地改善室内环境质量。
