摘要
植物对各种污染物都有吸收、积累、分解和代谢作用，降低大气中有毒气体的浓度，保持大气层中氧和二氧化碳的平衡，减少空气中的放射性物质，减弱躁声，杀菌除尘，净化环境污染；同时，由于不同植物对不同污染物的敏感性不同，又可用来监测预报环境污染。
The plants have the uses of absorption, concentration and metabolism to variors pollutants. They decrease the concentration of pollutant gases , keep the equillibrium of oxygen and carbon dioxide, abate noise and the radioactive substances in atmosphere, kill the bacterium and clean the dust. Meanwhile they can forecast environmental pollution by the sensitivities to various polllutants.
