铜胁迫对植物生理特性的影响概述
摘 要：铜元素是影响植物生理生化过程的重要微量元素，铜金属开采和使用的整个过程以及其所产生的废气、废渣、废水给周边生态环境的造成了严重污染，而矿区的开发对于土壤污染是最直接的，当铜元素在植物体内达到一定的量的时候，会对植物的生长发育以及生理生化带来严重的影响甚至导致植株死亡。本文综述了铜元素对植株光合参数，叶绿素含量，丙二醛的含量，抗氧化保护酶系统的影响。

Copper is an important trace element in plant physiological and biochemical process of copper mining and use of the whole process and the waste gas, waste residue, waste water has caused serious pollution to the surrounding ecological environment, and the development of mining area is the most direct for soil pollution, when copper reaches a certain amount in plants the will, the growth and development of plant physiological and biochemical bring serious influence and even lead to plant death. In this paper, the effects of copper on photosynthetic parameters, chlorophyll content, MDA content and antioxidant protective enzyme system were summarized.
