部分园林植物对大气污染物吸收净化能力的研究

Research on absorption and purgation ability to atmospheric pollutants of some garden plants

园林植物是城市生态环境的重要组成部分 ,具有净化空气、改善城市生态环境等多种功能。不同植物种类 ,因其生态功能上的差异 ,使其环保作用有显著的不同。本试验通过人工熏气方法 ,研究测定了部分园林绿化树种对主要大气污染物———二氧化硫、氯气和氟化氢的吸收净化能力。结果表明 :绿化树种对大气污染物具有一定的吸收净化能力 ,并依污染气体和树种的不同具有明显差异。

Garden plants are important constituent parts of urban ecological environment and have many functions such as atmosphere purification, urban environment improvement etc. Because there are difference in ecological function between different plants, environmental protection action of different plants are notable different. Based on artificially fumigated experiment, the paper study the absorption and purgation ability of some planting tree to main atmospheric pollutants--SO 2, Cl 2 and HF. The results show that the planting tree has certain absorption and purgation ability to atmospheric pollutants, and which widely varies with pollutant gas and planting tree.
