摘要:
我国耕地土壤受重金属污染严重，人们的健康受到深刻影响，而目前土壤重金属污染的治理仍有一定难度。本文以国内外大量有关重金属的研究为基础，从重金属的活性与分布、影响土壤重金属有效性的因素、重金属对作物生长发育的影响、作物对重金属的抗性以及重金属污染的治理修复方面进行综述，并对今后重金属污染研究的发展提出一些建议，以期为我国重金属污染的研究提供一些理论依据。
Abstract:
Soil contamination by heavy metals and the associated health problems resulting from foods pol-luted by heavy metals have been paid more and more attention in China. In this review paper, we summarized the activity and distribution of heavy metals, limiting factors for the availability of heavy metals in soil, influence of heavy metals on crop growth and development, crop resistance to heavy metals, and remediation of heavy metal pollution in agriculture. At the same time, some valuable strategies have been suggested to remediate heavy metal pollution in agriculture. This paper provided some theoretical basis for further studies on the heavy metal pollution in China.
