Abstract：[Background] With the rapid development of industrialization and urbanization, the continuous expansion of living space and production space has restricted the development of ecological space, and the contradiction among production, living and ecology is increasing. Watershed is a complex system integrating society, economy and nature, with production, living and ecological functions. As the largest river in Shanxi province, Fen river basin is also an important population and economic agglomeration area. In the long-term process of industrialization and urbanization, there are many problems in production-living-ecology space function. Exploring coupling coordination of production-living-ecology space function of Fen river basin plays an important role in the scientific and rational utilization and sustainable development of the land sources.[Methods] This paper took Fen river basin as the research area. According to the background characteristics of Fen river basin and referring to the relevant research results with similar regional characteristics,18 indicators were selected from three aspects of production function, living function and ecological function, and then the evaluation index system of spatial function of production-living-ecological in Fen river basin was constructed. Among them, the original data of each index was processed by the standardized method of non-zero transformation, and the weight was determined by entropy method. Finally, the coupling coordination model was used to quantitatively measure the coupling degree of spatial function, coupling coordination degree and coupling coordination degree between two pairs of production-living-ecological space in the Fen river basin in 2006, 2013 and 2018, and to analyze the spatial and temporal pattern and explore the causes.[Results] 1) In terms of the spatial and temporal pattern, the coupling degree presented the spatial characteristics of "low in the north and high in the south" and the embedding of low-value "patches", and the evolution trend showed the curve feature of "parabola with upward opening". However, the coupling coordination degree presented the pattern in which "patches" in high-value areas were embedded in low-value areas, while the evolution trend showed a "wave" curve feature. 2) The coupling degree of the production-living spatial function was high, but it was low in production-ecology and living-ecology space functions and went through the process of "high-decrease-increase", while the coupling coordination degree was at a lower level. 3) The main types, temporal and spatial characteristics and evolution of the coupling and coordination degree of the production-living-ecology space function in the study area were significantly affected by the spatial heterogeneity of the Fen river basin.[Conclusions] There are prominent contradictions among production-living-ecological space function in Fen river basin. Affected by the accumulation of ecological debt in the historical period, there is a great challenge to completely improve the coupling and coupling coordination of production-living-ecology space function in the short term. In the future, it is urgent to increase the research on the path of coordinated development of production-living-ecology space function in Fen river basin.
