Abstract: Revealing the synergies and trade-offs relationship between different functions of urban land is an important part of urban land use research. In this study, the POI data was used to measure the functional intensity of "production-living-commercial service" function of urban land within the third ring road of Wuhan. The pearson correlation coefficient and superposition method were employed to analyze the spatial and temporal patterns of the synergies and trade-offs relationship between different functions. The results showed that: (1) From 2015 to 2020, the spatial pattern of land production function intensity within the third ring road of Wuhan underwent a transition from centralization to decentralization. Meanwhile, the living function intensity gradually decreased from the urban center to the periphery. The commercial service function, on the other hand, exhibited a polycentric spatial pattern. (2) During the study period, the different functions of urban land in Wuhan predominantly exhibited weak synergies and trade-offs relationship, indicating a relatively independent development trajectory for each function. Specifically, from 2015 to 2020, while the correlation coefficients between the functions of production, living and commercial services passed the significance test, their values were all below 0.4 and showed a decreasing trend. (3) The synergies and trade-offs relationship between the different functions of urban land showed a significant spatial heterogeneity. The production and living functions of the urban land mainly exhibited a synergistic relationship in the urban center. The production and commercial service functions mainly showed a trade-off relationship.  The living and commercial service functions were intertwined, and there existed both synergies and trade-offs between them. (4) The synergies and trade-offs relationship between the different functions was formed under the joint action of social and economic development drive, policy planning guidance, natural condition constraints, and market mechanism incentives. In this study, we revealed the synergies and trade-off relationship between different urban land function. The findings can contribute to a deepened understanding of the characteristics of urban land use change, and provide scientific reference for spatial optimizing of urban land.
