合肥市大气污染对植物叶绿素(a、b)含量比例的影响

Effect of Atmosphere Pollution in Hefei City on Proportion of Chlorophyll of Plant Leaf

研究了安徽省合肥市城市大气对该市的 5种常见城市绿化植物叶绿素 (a、b)含量比例的影响 ,结果表明 :污染严重的市中心叶绿素a/b值最高 ,无污染的对照区叶绿素a/b值最低 ;通过t测验等数据分析方法 ,测出了石楠、龙柏、海桐具有显著的抗污染能力 ;比较了 5种植物之间抗污染能力的大小 :石楠 >龙柏 >海桐 >紫叶李 >

The effect of city atmosphere pollution on proportion of chlorophyll(a,b) was investigated in five common afforestion plants in Hefei city, Anhui Province. The results indicated that the numerical value of chlorophyll(a,b) in city center, which was heavily polluted, was the highest. Meanwhile, Sabina chinensis (L.) Ant CV. Kiaizuca, Pittosporum tobira Ait, Photinia serrulata Lindll showed remarkable ability of pollution tolerance through data analysis and test.What's more,the sequence of ability of pollution tolerance can be ranked as: photinia serrulata lindll, Sabina chinersis (L.) Ant CV.Kaizuca, Pittosporum tobira Ait, Prunus cerasifera Ehrh. F. atropurpurea Jacq, Ginkgo biloba L. So, it's helpful for the selection of tree species for city afforestion.
