建筑室内植物对空气净化能力的研究——2010年上海世博会“沪上·生态家”植物筛选

Study on Indoor Air Purification Ability of Plants——Plants Screening for Shanghai Eco-home of the World Expo 2010 China Shanghai

2010年世博会以"城市,让生活更美好"为主题,"城市最佳实践区"的首次设立是本次世博会的创举和亮点之一,"沪上.生态家"是唯一代表上海参展2010年上海世博会的实物案例项目。为达到环境宜居和室内环境达标率100%的目标,同时满足《绿色建筑评价标准》(GB/T 50378-2006)三星级绿色建筑标准,"沪上.生态家"团队以目前市场上较为常用的室内观赏植物为测试对象,建立了测试方法以研究其叶片部分在模拟甲醛超标环境中的甲醛净化效果,为"沪上.生态家"的植物筛选提供试验依据。研究发现不同植物对甲醛的吸收能力不同,净化效果存在差异:在24 h内试验的50种植物中,迷迭香单位叶面积净化甲醛量最多,黄金葛绿萝净化率最大;同时植物会使植物测试舱内的湿负荷增加。在测试结果的基础上,综合景观效益,选取了部分植物作为上海世博会"沪上.生态家"的室内观赏植物。

The theme of the World Expo 2010 China Shanghai was better city,better life,and the establishment of urban best practices area（UBPA） was one of the original and bright spot works.In UBPA,Shanghai Eco-home was the only selected project represented Shanghai to join the Expo 2010.In order to satisfy the Evaluation Standard for Green Building（GB/T 50378-2006） and achieve the livable environment,the market commonly used indoor ornamental plants were taken as the research objects,the purification effects of plants＇ leaves in the simulated excessive formaldehyde environment were studied.The measured results indicated that different plants had different absorption capacities of formaldehyde,also for the purification abilities.During the test period of 24 h and for all the 50 kinds of plants,the unit leaf area of rosemary had the largest ability to purify the formaldehyde and the scindapsus aureum had the largest purification rate.Meanwhile,the moisture load in the test chamber was increased due to the plants.Based on the comprehensive consideration of landscape benefits,several kinds of plants were selected as Shanghai Eco-home indoor ornamental plants.
