摘 要:识别国土空间多功能供给与居民需求之间的关系对实现区域“人-地”系统可持续具有现实意义。基于多源数据构建国土空间多功能供给与居民需求评价指标体系,而后利用供需匹配象限和供需弹性系数模型分析其供需平衡关系,借助空间关联模型识别供需源区和汇区的空间关联网络特征。研究发现:1)国土空间多功能综合供给能力表现为“四周高-中部低”,下降的格网占比达93.66%,各单项功能供给能力的空间分布及变化趋势存在较大差异,除城镇发展功能有所提高外,农业、生态功能均以下降为主。居民需求在空间上表现为圈层式由内向外递减的空间差异,提高的格网占比达88.21%。2)国土空间多功能综合供需表现为中部改善而东部恶化的静态匹配关系和以权衡为主导的动态耦合关系;在单项功能中,城镇发展功能供需以改善为主且多为协同关系;而农业和生态功能供需以恶化为主且多为权衡关系。3)国土空间多功能综合供需源区和汇区的空间关联强度略有降低。高级别的空间关联网络在城镇发展功能供需中表现为由北向南迁移,在农业功能供需中表现为由南向北迁移;另外,生态功能供需源区和汇区的空间关联强度明显下降。综上,国土空间各功能供给与居民需求的供需平衡关系存在空间差异,研究区应因地制宜地以居民需求为导向,强化国土空间多功能供给与居民需求趋同增进,深化可持续发展下各个区域的空间供需强关联。This study aims to accurately identify the supply and demand balance relationship,as well as the spatial correlation types between territorial space functions and residents’demand.Firstly,an evaluation index system was constructed on the territorial space functions using land use,population distribution,statistical and POI data.The multiple functions of land use were also focused mainly on the urban,agricultural and ecological aspects.Additionally,an evaluation index system was also developed on the residents’demand,according to the Maslow’s hierarchy of needs.Four dimensions were considered,including the survival,safety,social and respect/self-realization.This approach was used to evaluate the supply capacity of territorial space functions and residents’demand levels.The study area was taken as the Poyang Lake Ecological Economic Zone in 2014 and 2022.Subsequently,a systematic analysis was made to clarify the balance relationship between territorial space functions supply and residents'comprehensive demand using supply-demand matching quadrants and supply-demand elasticity coefficient models,from the static matching and dynamic coupling perspectives.Finally,the hot and cold spot analysis were employed to identify the sources and sinks for the territorial space functions supply and residents’demand.The gravity model was used to characterize the spatial correlation between these sources and sinks.The results showed that the spatial pattern of‘high around the edges-low in the center’was found in the supply capacity of territorial space functions.A predominant decreasing trend was temporally observed with a grid proportion of 93.66%.Among them,the high values of urban function were spatially distributed primarily in a point and linear pattern;Agricultural function also exhibited the spatial heterogeneity with the higher values in the south and lower values in the north;Ecological function decreased from both the northern and southern sides toward the center.Temporally,both agricultural and ecological f
