摘要

Cd contamination range of farmland soil in China is wide,which has constituted a major threat for food safety and residents’ health. Via multi-year development,there are more remediation methods suitable for soil contaminated by Cd among the world,but some methods are only suitable for the contaminated sites and indoor research,and can not be applied in large-range contaminated farmland. We analyze the source of Cd in farmland soil. By combining farmland’s characteristics,three remediation techniques( low-absorption crops plantation,soil solidification and phytoremediation) and their effects are analyzed,and the existing problems and research prospects of the above techniques are explored. The research could provide reference for restoring farmland soil contaminated by Cd in China,recovering its production function and enhancing food safety standards.
