摘　　要：通过对植物释放负离子的研究,筛选出可产生较高浓度负离子的室内植物,以保持和提高室内环境的负离子浓度,改善室内空气质量。在密封的玻璃室(80 cm×80 cm×80 cm)内对爵床科、龙舌兰科等24个科中的32种植物释放的负离子浓度进行测量,结果表明:大戟科的柳叶星点变叶木(Codiaeum variegatum)释放的负离子浓度最大达73 ion.cm-3,鸭跖草科的吊竹梅(Tradescantia zebrina)最低为16 ion.cm-3。以全天的均值来看,柳叶星点变叶木(Codiaeum variegatum)的负离子浓度为38 ion.cm-3最高,是对照试验的2.1倍。大部分植物在自然状态下产生的负离子浓度都表现出白天时段高于夜晚时段。植物在不同时段产生的负离子浓度值除个别植物变化幅度较大外,大部分植物在全天的浓度值都较为平稳。Generation of negative air ions（NAI） by indoor plants which belong to 24 families（Acanthaceae,Agavaceae,etc.） was studied.Those plants which can produce high concentration of NAI to maintain,even to increase the amount of NAI indoor was screened out.And they were capable of improving the quality of indoor environment.Measurements of NAI concentration generated by 32 species of plants were taken inside an airtight glass container.The results showed facts as following： Codiaeum variegatum produced 73 ion·cm^-3which was the highest while Tradescantia zebrina produced 16 ion·cm^-3the lowest.By mean of concentration in a whole day,Codiaeum variegatum respectively produced a highest level of 38 ion·cm^-3which was also 2.1 times as controlled experiment.In the state of nature,most plants produced higher NAI concentration during daytime than during night.And the concentrations of NAI generated by most plants kept steady at different times of day while a few plants kept larger rate of change in the concentrations of NAI.
