摘　　要：在我们国家的土地资源中,已经有两千万hm2以上的面积遭受到了汞、锌、铅和镉等重金属的侵害,也因如此造成了农作物收成降低、另外导致针对土地的应用率下降和对自然环境的破坏。因为重金属的主要特性为比较具有长久性、不容易移除、不容易被降解、危害性大,所以其对土地的生态体系与地下自然水质的循环体系将会带来严重的影响。笔者多年工作经验,对土壤重金属污染现状及修复技巧探讨提出了一些建议。In our country,more than 20 million hm2 of land resources have been damaged by heavy metals such as mercury,zinc,lead and cadmium,which have also resulted in the decrease of crop yield,the decrease of land use rate and the damage to the natural environment.Because the main characteristics of heavy metals are relatively long-term,not easy to remove,not easy to be degraded,great harm,so it will have a serious impact on the ecosystem of land and the circulation system of natural groundwater quality.Based on the author's working experience for many years,some suggestions are put forward on the status quo of soil heavy metal pollution and remediation techniques.
