| 摘 要：本文通过对大气污染物与植物含污量的关系的研究，对虎门地区大气环境进行了评价。研究结果表明，虎门地区大气污染有进一步恶化的趋势，而且氟污染比SO2染更严重。根据植物叶片污染指数(IPC)将虎门地区受污染程度划分为三个等级：重污染区(IPC³2.0)，中度污染区(1.5〈IPC≥)，和轻度污染区(IPC≤1.5)。划分的区域与大气监测结果相一致。 |

| 摘 要(英文)：The relationship between the air pollutant concentration and the pollutant contents in plant leave had studied, the results showed that air pollution status was trending to be worse. The environment polluted by fluorin or fluoride was more heavier than that by sulphur dioxide (SO2). According to the index of pollutant concentration (IPC) in plant leave, we separated air pollution around Humen area into three classes from light to heavy degree pollution: light degree polluted area (IPC£1.5); median degree polluted area (>1.5IPC<2.0) and heavy degree polluted area (IPC³2.0). The pollution status separated area by IPC were consistent with that status by atmosphere monitoring results. |
