| 摘 要： | 分析了我国部分主要城市农田土壤及农作物重金属污染状况，以了解土壤中与农作物中重金属污染物间的相互关系、变化趋势及造成污染的影响因素。结果表明，我国各大城市的农田土壤及农作物都存在不同程度的重金属污染，北方地区的土壤及农作物受重金属污染程度普遍高于南方。重金属在农作物与土壤中的含量一般呈正相关关系，受多种因素影响。对于已污染的土壤，可采用农业工程措施、生物修复法和施用改良剂等予以治理。

| Abstract: | In order to study the pollution of heavy metals in infield land crop and to fin d out effective prevention and remediation methods, we aim at finding the relati onship and trend between infield land soil and crop based on the analysis of sit uation about farm and crop around main cities in China in this paper. It is foun d that all infield lands and crops in these region are contamincted regarding he avy metals to a certain degree and that generally the infield lands and crops in southern China are more seriously contaminated than those in Northern China.It is showed that the heavy metal concentrations in infield land crops significathy correlated with those in soils.Agricultural engineering,bio-remediation and us ing modifier methods are applicable to improve the soil quality by removing heav y metals in soil. |
