Cultivated land protection and sustainable use in China:Challenges,solutions and prospects
[Purpose]The scientific protection and utilization of cultivated land provides useful references for ensuring national food security,land security and ecological security,and is of great scientific significance and policy importance.[Method]Based on a systematic literature study about the protection and utilization of cultivated land in China,this paper summarized the main problems,reviewed the relevant solutions,and provided a prospective analysis of future development.[Result]The total cultivated land in China was decreasing,accompanied by quality degradation and spatial fragmentation.To address these challenges,the paper summarized two major solutions,including policy regulation and scientific and technological innovation,with emphasis on the application of agricultural information technology.To better implement the solutions,the paper suggested refining the policy on sustainable development of cultivated land,strengthening scientific and technological innovation,and adopting integrated theoretical frameworks.[Conclusion]This paper discussed the future direction of the effective use and sustainable protection of cultivated land in China.Considering the food supply pattern in China is"ship grain from the north to the south",the paper suggests more efforts should be paid to the protection of the cultivated land resources in the north,particularly focusing on the conservation of the black soil in northeastern China and the improvement of salt-affected land in northwestern China.Equipped with the all-encompassing approach,the paper also suggests exploring the potential of grassland agriculture,aquaculture,and other available resources,ensuring China's fully self-sufficient in food supply.
