摘 要:耕地土壤污染是导致我国耕地质量下降、土地利用率降低、威胁国家粮食安全的一大主要因素。为了修复污染土壤,提高耕地质量,笔者从我国土壤污染的现实状况出发,分析了耕地土壤污染的主要来源,并重点分析了工业领域和农业领域产生土壤污染的主要诱因。在此基础上,提出了耕地土壤污染的修复方式,主要有物理修复方法、化学修复方法、生物修复方法、联合修复方法四种,并简要介绍了不同修复技术的应用原理、优缺点和适用方向。除此之外,还应当继续加大科技在土壤污染修复工作中的投入力度,以政府为主导,整合企业、高校以及群众等各方资源优势,协调工业和农业等范围内的污染物排放,以期从根本上缓解耕地土壤污染问题,为我国耕地保护和耕地质量提升提供一定思路。

Abstract: Soil pollution on arable land is a major factor leading to a decline in the quality of arable land, a decrease in land use efficiency, and a threat to national food security in China. In order to repair polluted soil and improve the quality of cultivated land, the author analyzed the main sources of soil pollution in arable land based on the current situation of soil pollution in China, and focused on analyzing the main causes of soil pollution in the industrial and agricultural fields. On this basis, four remediation methods for soil pollution in cultivated land were proposed, including physical remediation, chemical remediation, biological remediation, and joint remediation. The application principles, advantages and disadvantages, and applicable directions of different remediation technologies were briefly introduced. In addition, we should continue to increase the investment of technology in soil pollution remediation work, with the government as the lead, integrating the resource advantages of enterprises, universities, and the public, and coordinating pollutant emissions within industries and agriculture, in order to fundamentally alleviate the problem of soil pollution on arable land and provide certain ideas for the protection and improvement of arable land quality in China.

Keywords: cultivated land; soil pollution; heavy metals; repair measures
