摘要: 研究Cd、Pb、Cu、Zn、As复合污染对土壤植物系统的生态效应,供试污染物浓度以接近国内外土壤环境质量标准值作为高剂量处理.结果表明,该5种元素间可产生加和与协同作用,对生态系统造成危害.低剂量时,即可使土壤微生物活性受到抑制,高剂量时可使农作物减产10%,在酸性土壤上减产达50%以上,对苜蓿及树木也同样引起减产.

Abstract: The ecological effect of Cd,Pb,Cu,Zn and As compound pollution in soil plant system was studied in field plots. The designed concentration of pollutants was based on soil environmental standards or guidelines. The results show that there are interactions among these five elements, which cause a toxic effect on the ecosystem. The activity of soil microorganism is inhibited at low dose. At high dose, the crop yield is decreased by 10%, and on acid soil,by 50%. Alfalfa and tree are also yield decreased.

Key words: Compound pollution, Ecological effect, Heavy metals, ecosystem services flow, quantitative, ecosystem service value, supply and demand coupling
