摘　　要：随着城镇化进程加快,大面积的耕地资源损耗对区域粮食安全构成巨大威胁。协调好耕地资源保护和城镇化发展有利于促进区域的可持续发展。本文以宁波市北仑区为例,在获取有效数据的前提下,运用相关公式计算出该区2012-2016年各年度的耕地资源数量变化速率及城镇化水平演进速率,在此基础上利用协调度模型来评判二者的协同关系。结果表明:北仑区耕地资源面积与人均耕地面积均呈逐年下降态势,该区人均耕地资源面积远低于我国人均耕地资源面积的警戒水平,严重威胁区域粮食安全,不利于耕地资源的可持续利用;北仑区的城镇化发展已步入中期阶段,该区的工业基础较为雄厚,经济实力显著增强,农业劳动生产率大幅提高,工业化发展吸纳了大量农业人口,对当地就业水平的提高发挥了重要作用;北仑区耕地资源数量变化与城镇化水平演进呈现出勉强调和-不调和-调和-勉强调和的波动关系,耕地资源总体呈衰退趋势或勉强保持在承载力的阈值内,这种以牺牲耕地资源为代价的城镇化演进严重制约区域的可持续发展。基于此,提出以下建议:严禁建设占用耕地,对耕地资源实行用途管制;落实好耕地占补平衡制度,强调数量与质量并重;积极开展土地综合整治工作,增加后备耕地资源,确保区域粮食安全。With the acceleration of urbanization,the extensive loss of arable land resources poses a huge threat to regional food security.Coordinating the protection of arable land resources and urbanization development is conducive to promoting sustainable development in the region.This paper takes Beilun District,Ningbo City as an example.Based on obtaining effective data,relevant formulas are used to calculate the rate of change in the quantity of arable land resources and the evolution rate of urbanization level in the district from 2012 to 2016.On this basis,a coordination degree model is used to evaluate the synergistic relationship between the two.The results show that the area of cultivated land resources and the area of cultivated land per capita in Beilun District are declining year by year.The area of cultivated land resources per capita in this area is far below the warning level of the area of cultivated land resources per capita in China,which seriously threatens regional food security and is not conducive to the sustainable use of cultivated land resources.The urbanization development of Beilun District has entered the mid-term stage.The industrial foundation of the district is relatively strong.The economic strength has significantly increased.The agricultural labor productivity has greatly improved,and the industrial development has absorbed a large number of agricultural population,playing an important role in improving the local employment level.The changes in the quantity of arable land resources and the evolution of urbanization level in Beilun District show a fluctuating relationship of barely reconciling,not reconciling,reconciling,and barely reconciling.The overall trend of arable land resources is declining or barely maintaining within the threshold of carrying capacity.This urbanization evolution,which sacrifices arable land resources,seriously restricts the sustainable development of the region.Through this study,the following suggestions can be proposed:firstly,it is strictly prohibited to const
