Abstract: 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 functions shared the downward trend, except for an increase in urban function. Spatial pattern of single-core aggregation was observed in the residents’ demand level. The spatial difference also decreased from the center to the outside. There was the improvement in the central region, but deterioration in the eastern region, in terms of the static matching relationship between comprehensive territorial space functions supply and residents’ demand. The dynamic coupling relationship was dominated by the trade-offs. In terms of the individual territorial space function supply, all improvements were found in the static matching relationship between the urban function supply and residents’ demand. A dynamic coupling feature was dominated by the synergies. Conversely, there was the trend of the deterioration in the static matching relationship between the agricultural and ecological function. Their dynamic coupling relationships exhibited the trade-off characteristics. There was the slightly decrease in the spatial correlation intensity between the sources and sinks of comprehensive territorial space functions supply and residents’ demand. There were the great variations in the spatial correlation network for each individual function supply and demand. Specifically, the higher-level spatial correlation networks in the urban function supply and residents’ demand were shifting from the north to the south. In agricultural function supply, the higher-level spatial correlation networks were shifting from the south to the north. In summary, the spatial differences were observed in the supply and demand balance between various territorial space functions supply and residents’ demand. A location-specific approach can be expected to strengthen the alignment of territorial space supply with residents’ demand. The finding can also provide a strong reference for the balance between supply and demand in the regional ‘man-land’ relationship system.
