摘要
落实耕地占补平衡政策是保障我国粮食安全和生态安全的关键举措。本研究基于2022年中国288个地级市的统计数据,从理论与实践两个层面,综合考量补充耕地的适宜性和成本收益,运用模糊折衷型决策和成本收益测算制定耕地跨区域补充方案并提出对策建议。研究结果表明:(1)耕地跨区域补充的优先选择区域主要分布于黑龙江、吉林、辽宁、重庆和广西,这些区域应加大耕地保护力度,建议结合优先补充区的耕地生态服务价值与占用区经济发展水平设计动态耕地生态补偿机制。(2)耕地跨区域补充的中等适宜区域主要分布在中南部和西部地区,这些区域具有较大的发展灵活性,建议建立“耕地-经济弹性指数”,定期对耕地后备资源存量阈值与经济增速进行评估调整,当优先区的耕地后备资源充足时,可开展经济建设,反之则开展耕地补充。(3)不适宜作为耕地补充的区域主要分布在黄河以北、长城以南及渤海至东海沿线区域。黄河以北、长城以南区域,耕地本身质量不佳,建议开展土地综合整治,提升耕地质量,遏制耕地非农化。渤海至东海沿线区域是我国经济发达地区,补充耕地的成本高,应在保护耕地和生态环境的前提下发展经济建设,并对耕地补充优先选择区提供财政支持。
Implementing the cultivated land requisition-compensation balance policy is an important aspect of ensuring food security and ecological security in China.Based on the statistical data of 288 prefecture-level cities in China in 2022,this study comprehensively considered the suitability and cost-benefit of supplementing cultivated land from both theoretical and practical perspectives.Using fuzzy compromise decision-making and cost-benefit calculation methods,a cross-regional replenishment of cultivated land plan was formulated and corresponding countermeasures and suggestions were proposed.The results showed that:(1)The priority areas for cross-regional replenishment of cultivated land were mainly distributed in Heilongjiang,Jilin,Liaoning,Chongqing and Guangxi.These areas should intensify the protection of arable land and design a dynamic arable land ecological compensation mechanism in combination with the ecological service value of the arable land in the priority supplementation area and the economic development level of the occupied area.(2)The moderately suitable areas for crossregional replenishment of cultivated land were mainly distributed in the central-south and western regions.These areas had a certain degree of development flexibility.It is possible to establish an“arable land-economic flexibility index”to regularly assess and adjust the threshold of arable land reserve resources and the economic growth rate.When the reserve resources of cultivated land in priority areas are sufficient,economic construction can be carried out,otherwise,cultivated land replenishment can be carried out.(3)The areas that were not suitable for cross-regional replenishment of cultivated land were mainly distributed north of the Yellow River,south of the Great Wall and along the Bohai Sea to the East China Sea.The areas north of the Yellow River and south of the Great Wall were mainly characterized by poor quality of cultivated land.It is recommended to carry out comprehensive land improvement,improve the quality of cultivated land,and curb the nonagricultural use of cultivated land.The area along the Bohai Sea to the East China Sea is economically developed regions in China,and the cost of supplementing arable land is high.It is possible to develop economic construction while protecting cultivated land and ecological environment,and provide financial support for priority selection areas for cultivated land supplementation.
