摘要：通过对悬铃木(Platanus)在新乡污染区和相对无污染区生长的叶片中多种元素含量进行测定,分析了悬铃木对大气污染物的净化能力。结果表明,悬铃木在重度污染情况下能存活并且生长比较旺盛,与对照点相比,平均地径生长量下降了116.58%,高生长量下降了67.21%,冠幅生长量下降了213.43%。对含氯元素和氟元素的有害气体具有极强的抗性和净化能力,对Cl和F的吸收分别比对照高出237.14%和2233.30%;对As、Hg、Pb、Cd和Cr等重金属具有较佳的吸收能力,分别比对照高出97.11%、1 72.727%、733.918%、162.626%、174.176%。
In our study, we analyzed the purification capacity with Platanus between polluted areas and unpolluted areas in Xinxiang city by investigating a variety of element content in Platanus leaves.Our results indicated that Plat- anus could survive and grew in heavy contaminated areas vigorously. Compared with the control, average ground di- ameter growth decreased by 116.58%, and plant height declined by 67.21%.At the same time, crown growth was also lower by 213.43%. In the other hand, Platanus had a very strong resistance and purification to harmful chlorine and fluorine gases, which absorbed higher 237.14% chlorine and 2 233.30% fluorine than control. The absorptive capaci- ties to heavy metals, such as As, hg, Pb, Cd, Cr and so on, were higher by 97.11%, 1 172.727%, 733.918%, 1 162.626%, 174.176%, respectively.
