Phytotoxicity induced by copper was summarized. The community structure and diversity of the plants could be affected by Cu contamination. Oxidative stress and DNA damage caused by an excess of Cu in plant might be the most important mechanism of the phytotoxicity. So the toxicity of copper could be assesses by the bioavailability of Cu in the soil. The relationship of copper toxicity, oxidative stress and bioavailability in soil-plant system should be established.%介绍了土壤中铜污染对植物的影响,包括Cu污染对植物、植物群落、个体生长发育的影响,并分析了其影响机制.土壤Cu污染引起的植物毒性受到土壤中Cu的生物可利用性的影响,因此在评价土壤Cu污染的环境风险时应充分考虑土壤中Cu的生物可利用性,在土壤中Cu的生物可利用性、植物个体影响和群落变化之间建立联系.
