摘　　要：苯为室内空气污染的"三大隐形杀手"之一,严重威胁人们的生命健康,室内苯污染的生态治理已成为亟待解决的重要环境问题。室内植物对苯污染的抗性强弱与能力的研究与选择,是高效治理室内苯污染的基础和前提。叶绿素含量变化是评价室内植物对苯污染抗性强弱的重要依据之一。文章采用室内熏气实验,分析了9种常见室内植物在不同浓度的苯污染胁迫下植物体内叶绿素含量的变化,研究了室内植物对苯污染的抗性强弱。结果表明:植物种类、苯浓度及两者间的协同作用,对植物叶绿素含量变化的影响差异均达极显著水平;其中,苯浓度对植物叶绿素含量变化的影响更显著;在15、30和60 mg/m3浓度苯胁迫下,金边虎尾兰叶绿素含量分别降低5.43%、10.09%、19.33%,抗性能力最强;皱叶薄荷叶绿素含量分别降低12.81%、19.53%、35.18%,抗性能力最弱;在15 mg/m3浓度苯胁迫下,鸟巢蕨叶绿素含量降低5.92%,抗性能力次之;在30和60 mg/m3浓度苯胁迫下,绿萝叶绿素含量分别降低了10.33%、19.86%,抗性能力次之;综合评定结果表明9种室内植物对苯污染抗性能力最强的是金边虎尾兰,其次为绿萝,皱叶薄荷为最弱。Benzene has been known as one of the three invisible killers of indoor pollution,and is severely threatening human health,and the management of indoor Benzene pollution has become a major issue in improving indoor ecological environment. The indoor plants for adversity resistance to indoor Benzene,is essential to control benzene contamination efficiently. The research and choice of strength and ability of resistance of indoor plants to benzene pollution is the basis and premise of effective governance indoor benzene pollution. The change of the chlorophyll content of plants is one of the important bases to evaluate the ability of resistance to benzene contamination. The research does experiments with different concentrations of benzene stress for 9 plants with airtight fumigation method,by analyzing the changes in chlorophyll content under different concentrations of benzene pollution stress in plants, and does research on indoor plants resistant ability to benzene contamination. The results show that the influence of different plant species,benzene concentration and interaction between two factors on variation of the contents of chlorophyll have come to an extremely significant level; the effects of benzene concentration on plant physiological indexes’ changesis more significant; Sansevieria trifasciata var. laurentii has the highest resistance against benzene pollution under benzene stress of 15 mg / m3,30 mg /m3 and 60 mg · m- 3,which respectively is5. 43%,10. 09% and 19. 33%; Melissa officinalis,the lowest,which respectively is 12. 81%,19. 53% and 35. 18%; under benzene stress of 15 mg / m3,Neottopteris antique is the second to resist benzene pollution; under benzene stress of 30 mg / m3 and 60 mg / m3,the second is Scindapsus aureun. The physiological indexes of Sansevieria trifasciata var. laurentii has the strongest resistance to benzene pollution,followed by Scindapsus aureun,and the weakest is Melissa officinalis.
