摘　　要：本研究用封闭式熏气箱对5种植物的不同植物数量,以及不同种类配置吸收净化PM_(2.5)的能力进行了污染实验研究。结果表明,植物数量分别为2株时,净化PM_(2.5)能力为龙船花>五彩椒>发财树;4~6株时,净化PM_(2.5)的能力五彩椒>龙船花>发财树;8~10株时净化PM_(2.5)能力为:发财树>五彩椒>龙船花,在10株时,其两小时内最高吸收量分别为:118.43μg/m、113.10μg/m和91.10μg/m,不同数量各植物的吸收能力各有差异。每种植物2株,共6株搭配的净化效果最为显著,熏气箱PM_(2.5)消减量最高达到72.01μg/m;其次是4株发财树与2株五彩椒的搭配,吸收PM_(2.5)量为69.58μg/m。而且在上述3种植物,加上栀子花、花叶万年青植物,5种植物混合搭配,数量达到16株时,其吸收PM_(2.5)的量在2h内可以达到170μg/m,3h内的吸收PM_(2.5)的量可达到205μg/m。因此不同数量的植物,不同植物种类的组合配置对PM_(2.5)净化的能力是不同的,而且整体上表现为植物数量越多,吸收净化PM_(2.5)的量越多。这些为以后选取净化PM_(2.5)的植物和园林绿化及山地公园等建设工程的规划设计等方面提供科学依据和理论参考。In this study,3 plant species were carried out PM2.5 polluted tests with their different quantity,and different configuration of 3 species in closed fume box,used to analyze the ability of absorbing and purifying PM2.5 of different plants,different plant numbers and differentplant combinations. The results showed that when two numbers of each plant,the absorbing and purifying PM2.5 ability were Ixora chinensis 〉Capsicum annuum 〉 Pachira macrocarpa; when their numbers were four and six,the effect of reducing PM2.5 were Capsicum annuum 〉Ixora chinensis 〉Pachira macrocarpa. In 8 or 10 numbers of plant,the absorption ability of PM2.5 were Pachira macrocarpa〉Capsicum annuum〉Ixora chinensis; the most absorbed quantity in two hours were 118. 43μg/m,113. 10μg/m and 91. 10μg/m. The most absorbed quantity of PM2.5 in 3 species mixed configuration with every species 2 pots was 72. 01μg/m,the effect of absorbing PM2.5 which was mixed with 2 pots of Ixora chinensis,2 pots of Pachira macrocarpa and 2 pots of Capsicum annuum was best; the second was the effect of absorbing PM2.5 which the group was mixed 4 pots of Pachira macrocarpa and 2 pots of Capsicum annuum,reduced 69. 58μg/m of PM2.5; and then 5 species of configuration with increase Gardenia jasminoides and Dieffenbachia picta,the number of plant reached 16,their absorbing quantity of PM2.5 in two hours could reached 170μg/m,and reached 205μg/m in three hours. These indicated that the ability was different with different number of plant and different plant configuration,but showed that with the plant number more,the quantity of absorbing PM2.5 are more. these provided scientific basis and theoretical reference for the planning,design of garden greening and mountain park in aspect of using plants purify PM2.5 in the future.
