农田土壤重金属污染及调控措施

摘要

农田土壤重金属污染是全世界所共同面临的普遍性环境问题之一.从农田土壤重金属污染的来源,重金属污染对农田土壤质量、作物生长发育、农产品品质以及对人类健康的影响,论述了重金属污染的防控与调控措施,主要有物理和化学调控、植物修复和农业生态修复措施,并对以后的研究方向进行了探讨.%Soil pollution has been considered as one of the main environmental problems in the world nowadays. The source of soil heavy metal pollution in farmland, the effect of heavy metal pollution on soil quality in farmland, growth of crops, quality of agricultural products and on human health were discussed in this paper. The heavy metal pollution control measures were introduced, including physical and chemical regulation, phytoremediation and agroecological restoration measures. The future research direction is also discussed in this paper.
