摘要
南阳市大气对该市5种常见城市绿化植物叶片叶绿素(a、b)含量比例(Ca/Cb)以及叶片叶绿素总含量(Ct)有影响。通过研究发现:污染严重的南阳卷烟厂区域植物叶绿素Ca/Cb值相对较高,叶绿素总含量(Ct)相对较低;无污染的对照区域(南阳师范学院院内绿化区)植物叶片叶绿素Ca/Cb值相对较低,叶片叶绿素总含量(Ct)相对较高。通过数据分析,进一步测出了女贞、大叶黄杨、月季具有显著抗大气污染能力,并比较了5种常见城市绿化植物之间抗大气污染能力的大小:女贞>大叶黄杨>月季>金叶女贞>三叶草。
The effect of city atmosphere pollution on proportion of chlorophyll（ a, b） and the content of chlorophyll of five common plants were investigated in Nanyang city of Henan province. The result showed that in heavily polluted area （ Nanyang cigarette factory）, the ratio of plants chlorophyll（ a, b） was higher and the content of chlorophyll was less, compared with Nanyang Normal University, pollution-free area. Meanwhile, Ligustrum licidum Ait. ,Euonymus japonicus,Rosa chnensis jacq. showed notable ability of pollution tolerance through data analysis and test. What＇ s more,the ability of pollution tolerance can be ranked as： Ligustrum licidum Ait. ,Euonymus japonicus, Rosa chinensis Jacq. , Ligustrum vicaryi, Trifolium pratense.
