Abstract: Optimizing the spatial layout of the production-living-ecological at the village scale and revealing the spatial and temporal changes in the functional coupling and coordination of the production-living-ecological in the countryside are the prerequisites for realizing the revitalization and sustainable development of the countryside. Based on the village scale, this paper took Changling Town, Guangshui City, located in the low hilly region of northern Hubei, as the research area. The spatial and temporal change characteristics of the tertiary space from 2000 to 2020 were analyzed, based on the land use transfer matrix. The tertiary space function was explored using the coupling coordination degree model. The main driving factors was studied using the geographic detector. The study was expected to provide an effective reference for the sustainable development of rural areas, territorial space governance and ecological environment protection at the subsequent village scale. The results showed that: (1) the living space and production space of Changling Town in Guangshui City expanded from west to north during 2000-2020; (2) The coupling coordination degree of the production-living-ecological space in Changling Town of Guangshui City was in a relatively stable trend, and the overall was in a moderate state of imbalance; (3)Land use intensity was the most important driving factor that affected the spatial differentiation of the coupling coordination degree, followed by the proportion of cultivated land area and population density and other secondary factors. In general, the spatial and temporal variation of the coupling coordination degree was greatly affected by human activities.
