土壤重金属污染现状及生态修复路径分析

Present Situation Analysis of Soil Heavy Metal Pollution and EcologicalRestoration Path

土地作为国家最重要的农业资源,对种植业有着举足轻重的意义。一旦土地受到重金属污染,将极易导致植物的基因突变,进而抑制植株的正常生长发育。中国的土壤污染主体是耕地污染,因其污染源具有很大差异性,所以需要不同的恢复技术,或通过划定风险管控范围进行土地恢复。本文就有色重金属污染土地恢复关键技术以及修复实践进行研究,希望能为有关工作提供借鉴。

As the most important agricultural resource in the country,land plays an important role in promoting of planting industry in China.However,once the land is polluted by heavy metals,it will easily lead to genetic mutation of plants,and then inhibit the normal growth and development of plants.The main body of soil pollution in China is cultivated land pollution.Because the pollution sources are very different,it is necessary to restore the technology differently,or to restore the land by delineating the scope of risk management and control.This paper studies the key technology and practice of restoration of land contaminated by colored heavy metals,hoping to provide reference for related work.
