Abstract: 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.
