污染土地修复工程技术及发展趋势

近年来，中国土地污染状况日益凸显，加剧了土地资源供需矛盾，耕地土壤污染给农民带来了经济利益和健康利益的双重损害。为缓解矛盾，保护粮食安全，保证耕地红线，增加建设用地，如何利用工程技术手段将污染土地变为可利用土地显得尤为重要。通过文献资料法，结合多年来污染土地治理修复的工程技术经验，对污染土地修复工程技术要点进行了探讨和总结，主要介绍中国土壤污染发展现状，以及如何将污染土地变为可利用土地，最后展望了中国污染土地修复工程技术的发展趋势。该研究为提出适合中国国情和符合地区特点的土壤污染修复技术奠定了理论基础，同时为国家粮食安全、生态文明建设提供技术支撑。

Engineering Technology and Development Trend of Polluted Land Restoration

In recent years, land pollution is increasingly highlighted in China, it intensifies the contradiction between supply and demand of land resources, and farmland soil pollution has brought double damages to economic and health benefits of farmers. In order to alleviate the contradiction, protect food security, guarantee the red line of arable land and increase the construction land, turning polluted land into available land by engineering technology is important. Through literature review and based on many years’ experience of using polluted land restoration engineering technology, the authors discussed and summarized technical key points of polluted land restoration project, introduced the developing situation of soil pollution, and the approaches to turn the polluted land into available land. Finally, the authors made an outlook on the development trend of polluted land restoration by engineering technology in China. The study laid a theoretical foundation of soil pollution restoration technology according to China’s national conditions and regional characteristics, at the same time provided technical support for the country’s food security and ecological civilization construction.
