城市森林植物修复污染土壤的功能

The Function of Phytoremediation for Urban Forest Plants on Pollutants in Soil

主要论述了不同森林植物通过自身理化特性吸收和转移土壤重金属 ,实现修复污染土壤的功能。重点从修复重金属污染土壤、降解土壤中的TNT以及修复被多环芳烃 (PAH)污染土壤等功能方面进行了综述 ,并列举了部分植物Zn、Cu、Cd、Pb、Ni、Hg等重金属的富集能力。为城市不同重金属污染条件下的城市森林建设植物材料选择提供了参考。

The remediation function of urban forest plants is systematically reviewed, which is realized by absorbing and translating heavy metal in the soil as a result of the physical and chemical characteristics for plants. The functions of remedying heavy metal and PAH as well as degrading TNT in the soil were emphatically reviewed, and the hyperaccumulation of Zn, Cu, Cd, Pb, Ni, Hg of some plants were illuminated. The study can offer some reference for the selection of urban plant species in the condition of pollution by heavy metal.
