摘　　要：[目的]研究耕地“生产-生活-生态”功能间发展不平衡现状,提出分区权衡管理措施,对促进耕地可持续利用水平和推动区域耕地保护政策实施具有重要意义。[方法]利用新疆85个县市2005-2020年社会经济数据,构建耕地多功能评价体系,基于改进CRITIC-熵值法确定指标权重,运用综合指数模型、Spearman秩相关和双变量空间自相关模型对新疆耕地多功能进行评价,分析了耕地多功能的时空特征及其权衡协同关系,并将新疆划分为五大耕地利用功能区。[结果](1)耕地生产、生活、生态功能分别呈现“中间高,南北低”“北高南低”“三高夹两低”的空间分布特征。(2)耕地多功能间存在显著权衡关系,研究期内生产-生活功能权衡关系减弱,而生产-生态和生活-生态功能权衡关系增强。(3)基于以上结果,将耕地功能区划分为农业生产主导区(25.88%)、农业发展提升区(12.94%)、生态农业维持区(45.88%)、协同潜力提升区(5.88%)、城镇农业建设区(9.41%),优化新疆耕地利用格局。[结论]基于耕地功能分区提出差异化权衡管理措施,有利于保障粮食安全,对新疆耕地保护及多功能协同利用有一定借鉴意义。[Objective]The aims of this study are to examine the current imbalance in the development of‘production-living-ecological’functions of cultivated land,propose zoning trade-off management measures,to promote the sustainable use of cultivated land,and to drive the implementation of regional cultivated land protection policies.[Methods]The Socio-economic data from 85 counties and cities in Xinjiang from 2005 to 2020 were utilized to construct an evaluation system for the multifunctionality of cultivated land.The improved CRITIC-entropy method was used to determine index weights.Comprehensive index models,Spearman rank correlation,and bivariate spatial Moran′s I were employed to evaluate the multifunctionality of cultivated land in Xinjiang.The spatiotemporal characteristics and the trade-off and synergy relationships of the multifunctionality of cultivated land were analyzed.Xinjiang was divided into five major functional areas for cultivated land use.[Results](1)The production,living,and ecological functions of cultivated land exhibited spatial distribution characteristics of‘higher level in the middle,lower level in the north and south’,‘higher level in the north,lower level in the south’,and‘three high areas surrounded by two low areas’respectively.(2)There were significant trade-offs among the multifunctions of cultivated land,with the production-living function trade-off weakening during the study period,while the production-ecological and living-ecological function trade-offs had intensified.(3)Based on these findings,the functional areas for cultivated land use were divided into agricultural production dominant areas(25.88%),agricultural development enhancement areas(12.94%),ecological agriculture maintenance areas(45.88%),synergy potential enhancement areas(5.88%),and urban agriculture construction areas(9.41%),to optimize the pattern of cultivated land use in Xinjiang.[Conclusion]Proposing differentiated trade-off management measures based on the functional zoning of cultivated land is ben
