摘　　要：研究目的:揭示2021年武汉市“农业生产—非农生产—生活—生态”土地利用功能系统间的权衡协同关系,探索不同主体功能情形设定下驱动因子的影响差异性,为促进当地土地资源的优化利用与空间精细化管理提供参考依据。研究方法:地理空间分析法,皮尔逊相关系数法,贝叶斯网络模型。研究结果:(1)武汉市不同土地利用功能空间分异特征明显,农业生产功能的高值与较高值主要集中在武汉市北部与南部地区,非农生产与生活功能基本呈现“中心城区高、远城区低”的特征,生态功能的低值、高值分布特征则与建设用地、林地等土地利用类型高度关联;(2)研究区非农生产与生活功能互为协同关系(r=0.84),农业生产与非农生产功能(r=-0.25)、生活功能(r=-0.25)互为权衡关系,生态功能与非农生产功能(r=-0.36)、生活功能(r=-0.4)互为权衡关系,生态与农业生产功能则无明显相互关系(r=-0.027);(3)人类活动强度、距区中心远近、土地利用强度、地表径流量是影响当地土地利用功能差异化发展的关键驱动因子,且在不同主体功能情形设定下,各因子的状态变化不尽相同。研究结论:武汉市应注重不同区域间的非农生产、生活功能平衡发展,通过建成区的生态宜居建设与城乡均衡发展改善土地利用功能间的权衡关系,并基于不同地区的主体功能制定差异化的管控策略。The purposes of this study are to reveal the trade-offs and synergy relationship among agricultural production,non-agricultural production,living and ecological land use functions(LUFs)in Wuhan in 2021,to explore the differences in the impact of driving factors under different dominant function settings,and to provide references for promoting the optimal utilization and spatial refinement management of local land resources.The research methods include geospatial analysis,pearson correlation coefficient and Bayesian Network model.The results indicate that:1)LUFs of Wuhan exhibits significant spatial differentiation.Areas with higher values for agricultural production function are mainly concentrated in the northern and southern regions of Wuhan.Non-agricultural production and living functions generally show a“higher value in the central urban area,lower value in the suburbs”pattern.While the distribution of low and high values of ecological function is closely associated with land use types,such as construction land and forests.2)In the study area,there is a synergy relationship between non-agricultural production and living functions(r=0.84).Agricultural production is in a trade-off relationship with non-agricultural production(r=-0.25)and living(r=-0.25)functions.Ecological function is in a trade-off relationship with non-agricultural production(r=-0.36)and living(r=-0.4)functions.However,there is no apparent mutual relationship between ecological and agricultural production functions(r=-0.027).3)The key driving factors of the differentiated development of LUFs include human activity intensity,distance from the central urban,land use intensity and surface runoff.Additionally,the status changes of these factors vary under different dominant function settings.In conclusion,Wuhan should pay attention to the balanced development of non-agricultural production and living functions in the different areas.To ameliorate the tradeoffs relationship between LUFs,ecological livable construction in built-up areas and bal
