摘　　要：植物具有对大气污染反映灵敏的特点,当植物吸收污染物并积累到一定程度时,植物即发生中毒,引起外部形态和生理活动异常。广泛存在于植物体内的过氧化氢酶是一种很重要的酶,当植物受到大气污染时,其体内过氧化氢酶活性明显降低。在合肥市选定四个样点,分别采集四个采样点的女贞叶片,通过测定植物叶片中过氧化氢酶活性,可初步反映合肥市的大气污染现状,对合肥市的大气质量进行监测与评价,并提出利用植物监测大气环境中污染的几点建议。Plants have relatively high sensitiveness to air pollution. When plants assimilate pollutant to the extent that they are poisoned,their appearance and physiological activity will be influenced. Hydrogen peroxidase which distributes in plant widely is an important enzyme. Activity of hydrogen peroxidase would decrease obviously when plants were polluted. Four sampling points were selected in Hefei city,and leaves were gathered from Ligustrum lucidum Ait. respectively. Atmosphere pollutional current situation could be reflected basically by analyzing activity of Hydrogen peroxidase in leaves. It could help us monitor and appraise atmosphere quality in Hefei city.And we put forward some advice about utilizing plant to monitor atmosphere pollution.

关 键 词：植物监测 大气污染 过氧化氢酶
