摘　　要：研究目的:揭示沈阳市耕地多功能时空演变格局及功能间权衡协同关系,探讨格网尺度下耕地功能组合分区方案,为耕地多功能协调发展和空间合理布局提供实施路径和理论借鉴。研究方法:用斯皮尔曼和空间自相关分析方法。研究结果:(1)2006—2020年沈阳市耕地功能呈现不同变化趋势。耕地生产保障功能处于较高水平,2006年和2020年Moran’s I分别为0.973和0.766,社会保障功能持续增加,其Moran’s I由0.485上升为0.564。(2)耕地功能间自相关整体显著权衡且片状分布,协同程度呈增强趋势,局部权衡协同空间格局存在重叠特征。(3)根据耕地多功能权衡协同演变特征,可将沈阳市耕地划分为单功能主导区,双功能协同区、多功能协同区、高协同区和低协同区。研究结论:沈阳市耕地多功能权衡协同区具有明显空间异质性和重叠性,通过对不同分区内耕地多功能优化组合,可实现对耕地资源的科学保护和合理利用。The purposes of this study are to reveal the spatial and temporal evolution pattern of cultivated land multifunction and the trade-off and synergy between functions in Shenyang City,and to explore the zoning scheme of cultivated land function combination under the grid scale,to provide the implementation path and theoretical reference for the multifunctional coordinated development and the rational spatial layout of cultivated land.The research method is Spearman and spatial autocorrelation analysis.The research results show that:1)the spatial distribution heterogeneity of cultivated land function is obvious.The security function of cultivated land production is at a high level.In 2006 and 2020,the Moran’s I was 0.973 and 0.766,respectively.The social security function continued to increase,and its Moran’s I increased from 0.485 to 0.564.2)The autocorrelation between cultivated land functions is significantly balanced and distributed in patches,and the degree of synergy is increasing.The spatial pattern of local trade-offs has overlapping characteristics.3)According to the characteristics of the coordinated evolution of multifunctional trade-off of cultivated land,the cultivated land in Shenyang City can be divided into single function dominant area,dual function collaborative area,multifunctional collaborative area,high collaborative area and low collaborative area.In conclusion,the multifunctional trade-off and coordination area of cultivated land in Shenyang City has obvious spatial heterogeneity and overlap.Through optimizing the multifunctional combination of cultivated land in different zones,the cultivated land can be scientifically protected and rationally utilized.
