摘 要:土地整理是实现耕地总量动态平衡,保证国家粮食安全的重要措施。当前,我国的土地整理已从单目标的增加耕地面积向提高农业综合生产能力、改善生态环境、促进城乡发展的多目标方向发展。因此,科学合理测算土地整理潜力是目前迫切需要解决的问题。在耕地整理数量潜力基础上,结合农用地产能核算成果,对耕地整理质量潜力的确定进行了探讨,并以卢龙县为例进行了实证研究。通过对耕地整理数量和质量潜力的综合分区,计算得出耕地整理近期可实现利用潜力1.36万t,远期理论利用潜力4.55万t,并划分出卢龙县近期耕地整理重点区域和远期耕地整理重点区域。Land consolidation is the important measure of realizing the farmland total dynamic balance and ensuring the national food grains safety. At present,the main aim of land readjustment in our country will be changed from merely adding arable land to multipurpose development direction of promoting agricultural comprehensive productive ability,improving ecological environment and urban and rural development.So how to reasonably analyze readjustment potentiality becomes an essential item.On the basis of theries of land consolidation,by using the combinated results of agriculture land productivity calculation,making pricing methods for qualitative potential of land consolidation,and was implemented in Lulong County.Through making comprehensive zoning of land consolidation quantity potential and quality potential,showing that the recent realization potential of land consolidation was 13.6 thousand tons,and the forward quality potential was 45.5 thousand tons,finally divide out the priority area of the recent and forward land consolidation in Lulong county.
