摘　　要：为选择适宜新居装修中植物,净化新居环境,研究了四种常见的室内观叶植物:常春藤、绿萝、大叶万年青、吊兰对苯污染的吸收能力及其光合对苯污染的响应。结果表明:4种植物对苯污染均具有一定的净化效果,其净化能力大小表现为常春藤>绿萝>大叶万年青>吊兰。苯污染造成4种植物叶片叶绿素含量下降,其中吊兰下降最多。苯污染下,4种植物叶片光合速率、PSⅡ最大光化学效率(Fv/Fm)下降,以常春藤下降幅度最小,其余植物反应不一。综合比较,认为4种植物中常春藤是清除苯污染较理想的选择。In order to select proper plants for their new residence and purify indoor environment. The ability of removing benzene of Hedera nepalensis var. sinensis , E pi premnum aureum ,Rohdea japonica var. lati f olia and Chlorophytum comosum were investigated. Chlorophyll content and leaf net photosynthetic rate were analyzed. The results showed that four kinds of indoor foliage plants all had certain absorptive capacities on benzene,the ability of absorbing benzene declined as.. Hedera nepalensis var. sinensis〉Epipremnum aureum 〉Rohdea japonica var. latifolia〉 Chlorophytum comosum. Benzene reduced the contents of chlorophyll, the chlorophyll drop of Chlorophytum comosurn was the most. Leaf net photosynthetic rate and fluorescence parameter Fv/Fm were reduced under benzene stress. But the trends in changes were different in different plants. In conclusion, Hedera nepalensis var. sinensis was the optimum choice for benzene purification among four kinds of plants.
