Abstract：The Huaihe River Basin is an important grain production base and coal supply base in China.However,coal mining activities have led to surface subsidence in mining areas,reduction of cultivated land area,decline in fertility,increase in soil environmental risks,and decrease in carbon sequestration potential.The current situation of the quantity,quality and ecological damage of cultivated land in the coal mining areas of the Huai River Basin was systematically sorted out,the damage mechanism was analyzed,and the research progress of domestic and foreign scholars in the quantity regulation,quality improvement and ecological restoration of damaged cultivated land in recent years was mainly reviewed.Coal mining leads to a reduction in the quantity of cultivated land,a decline in its quality and damage to the ecosystem.However,through comprehensive measures such as green mining technology,land reclamation technology,improved farming methods and bioremediation technology,the problem of cultivated land damage can be effectively alleviated.In the future,the integrated technical system for regulating cultivated land should be further optimized,the source protection of cultivated land and the governance of the coal mining process should be strengthened,the coordinated development of coal mining and cultivated land protection should be promoted,the synergy of ecological restoration of damaged cultivated land and the carbon sinks should be enhanced,and long-term monitoring and pre-assessment should be strengthened to ensure regional food security,energy security and sustainable development.
