摘　　要：基于天津1992—2022年4期数据,运用重心模型、探索性时空数据分析等方法,分析了大都市区耕地非农化时空跃迁特征。结果表明:天津耕地非农化主要以转为建设用地、水域为主;天津耕地非农化地域差异明显,中心城区耕地非农化规模较小,而东南各区规模较大;天津耕地非农化重心先向西北后向东北方向迁移,总体呈“V”型走势;天津耕地非农化有明显的空间集聚特点,但聚集水平不断下降,“高—高”聚集区主要分布于东部及南部区域,“低—低”聚集区主要分布于中心城区;北部、东部和南部地区的耕地非农化空间结构有较强的动态性,北辰区、东丽区等中心城区周边区对临近区有更强空间依赖;天津耕地非农化在空间格局演化上具有较强的空间整合性,正向协同增长的有7个区,主要分布在中北部地区,负向协同增长的有3个区,主要分布在中心城区周边区域;天津耕地非农化的不同空间结构类型间较少发生跃迁,具有较强的转移惰性。Based on data from four periods between 1992 and 2022 in Tianjin city,by using the gravity center model and exploratory spatiotemporal data analysis methods,spatiotemporal transition characteristics of cultivated land non-agriculturalization in the metropolitan area have been analyzed.It is indicated that the cultivated land non-agriculturalization in Tianjin primarily involves conversion to construction land and water bodies.Significant regional disparities exist,with smaller scales of non-agriculturalization in the central urban area and larger scales in the southeastern districts.The gravity center of farmland non-agriculturalization in Tianjin initially shifted northwest and subsequently northeast,displaying an overall"V"shaped trajectory.The non-agriculturalization process demonstrates clear spatial clustering,although the level of clustering is gradually diminishing."High-high"clustering areas are predominantly located in the eastern and southern regions,while"low-low"clustering areas are mainly found in the central urban area.The spatial structure of cultivated land non-agriculturalization in the northern,eastern and southern regions exhibits strong dynamism,while Beichen district and Dongli district around the central urban area show a stronger spatial dependence on adjacent districts.The spatial pattern evolution of cultivated land non-agriculturalization in Tianjin reveals a robust spatial integration.7 districts show positive coordinated growth primarily in the north-central region,and 3 districts exhibit negative coordinated growth mainly located around the central city.There is minimal transition between different spatial structure types of cultivated land non-agriculturalization in Tianjin with strong transition inertia.
