[Objective] The aims of this study are to elucidate the relationship between the production-living-ecological functions in Hubei Province and the role of their influencing factors on the spatial layout of the territorial space, and to provide theoretical support for optimizing the development and protection pattern of the territorial space. [Methods] The framework of ‘function evaluation-quantification of relationships-identification of mechanisms' was follows to evaluate the production-living-ecology functions based on the grid scale, and the root mean square error(RMSE)model and geographical detector model were used to explore the spatiotemporal pattern and influencing factors of spatial functional trade-off relationships, respectively, which broke through the limitations of existing studies on the dynamic evolution of spatial function relationships at the microscopic scale. [Results](1)From 2000 to 2020, the production and living functions of the region had been improved, with significant changes in the high areas of Wuhan City and low areas of the western mountainous areas of Hubei, expanding by 538.54 km2 and 14 207.47 km2 respectively. The overall ecological function had weakened, and the reduction in the high areas of the four mountainous regions had been marked, with an average annual decrease of 1 009.50 km2.(2)During the study period, the intensity of production-living function trade-off was characterized by a ‘Λ'-shaped evolution, and the spatial layout showed an ‘expansion of low-value areas and contraction of high-value areas', especially in the central and western parts of Suizhou City and the main urban area of Wuhan City. The change patterns of production-ecological function intensity and living-ecological function intensity were similar, with an inverted N-shaped evolution trend, but the spatial distribution pattern differed significantly, showing a ‘high in the middle and low around' distribution pattern and a center-periphery spatial layout, respectively.(3)In 2000—2005, 2005—2010, 2010—2015, and 2015—2020, the dynamic changes of the production-life function trade-off index were especially prominent in the main urban areas of one provincial center of Wuhan and two provincial sub-centers of Xiangyang and Yichang, some counties and districts of Wuhan Metropolitan Area and mountainous areas of western Hubei Province. The significant changes of production-ecological function trade-off index and living-ecological function trade-off index mainly distributed in four mountainous areas and some counties and districts of Jianghan Plain in Hubei Province.(4)Population density, GDP, and human activity intensity were the main drivers of the territorial spatial functional trade-off relationship. [Conclusion] The overall level of synergy among the production-living-ecological functions in Hubei Province is improving, and socio-economic activities have a greater impact on the coordinated development of the production-living-ecological functions, which should be followed up by strengthening the territorial space control and management in accordance with the local conditions.
