With the development and modernization of rural economies, the integration of agriculture, cultural tourism, and other fields has gradually become a new driving force for promoting rural revitalization. However, in recent years, the development of mines and the utilization of resources have led to severe heavy metal pollution of farmland soil, causing significant food safety risks and economic losses, which pose serious challenges to the integration of agriculture, culture, and tourism. Therefore, China has invested a lot of attention in addressing the issue of soil remediation in abandoned rural mining areas. The study focuses on an abandoned mining area polluted by heavy metals such as Cd, Zn, and Cu in a certain area. Two materials, biochar and compost, were added to the soil in the polluted area, and the weight ratios of biochar and compost were set to 0:100, 10:90, 20:80, 40:60, 60:40, and 100:0. A new type of biochar was prepared by mixing two materials at high temperatures, and its effects on the pH and organic carbon content of soil in heavy metal polluted rural abandoned mining areas were explored. The effective removal and adsorption of heavy metals in the soil were also investigated, as was the promotion of crop growth in the soil area. This indicates that the use of biochar and compost can significantly repair heavy metal contaminated soil in mining areas and improve soil availability. Meanwhile, research has found that the integration of agriculture, culture, and tourism provides a unique perspective on soil remediation technology, which may involve maintaining rural cultural traditions, enhancing the attractiveness of rural tourism, and ensuring food safety and agricultural sustainability. Therefore, the selection and implementation of repair technologies need to consider multiple factors to ensure the triple benefits to the economy, society, and environment.
