摘要：随着世界经济的高速发展,大量工矿企业也随之产生,这些工矿企业所产生大量含有重金属的物质经过一定处理或未经处理被直接排放到大自然中,这些物质会直接或间接对土壤造成严重污染。植物对重金属有一定的吸收能力,但超过一定的耐受值,就会对植物产生毒害作用,不同植物其耐受值不同,重金属在植物体内的分布也不同。而在倡导低碳、绿色的今天,利用植物来修复土壤中的重金属污染物质具有成本低、修复效果好、不会对土壤造成二次污染的特点,这是其他修复方法所不具备的特点与优点。但该方法仍是一项刚刚兴起的修复技术,仍有诸多问题需要解决。
With the rapid development of world economy, a large number of industrial and mining enterprises arise, these enterprises produced a large number of containing heavy metal material after a certain processing or untreated by direct emissions into the environment, these material would cause serious pollution to soil directly or indirectly. Plants had certain absorption capacity of ＇heavy metals, but when beyond a certain tolerance value, it would be toxic to plants. Today, we, initiate Low - carbon and green, Phytoremediation has low cost, effects are better and will not cause secondary pollution to soil characteristics and advantages, these are other methods don＇t have. But this method is still a newly emerging technology to repair, there are still many problems need to be solved.
