【摘要】 综述了土壤重金属污染的危害,牧草作为修复植物的优势,以及主要牧草对重金属污染土壤的修复效果。提出了进一步筛选重金属富集能力强的牧草品种,寻找各种改良措施提高牧草的修复能力将是今后的研究热点。同时,人们应该更加关注植物修复的后期处理,尤其是解决从植物体内回收重金属的生产工艺问题。更多还原

【Abstract】 This paper summarized the harms of soil heavy metals pollution,the advantages of using forage grass as remediation plant,and the effects of main forage grass species in phytoremediation of heavy metals-contaminated soils. To select the forage grass species with strong capability in accumulating heavy metals and to search for various kinds of measures to raise the phytoremediation capability of forage grasses would be the research hotspots,and the post-processing of phytoremediation,especially the production techniques of recycling the heavy metals from plants,should be more concerned with.更多还原
