[目的] 探究山西省不同县域“三生”功能时空动态演化特征并分析其影响因素，为国土空间规划提供依据。[方法] 基于山西省107个县2005，2010，2018年土地利用类型和统计数据，采用综合指数模型、动态度和空间计量模型分析其“三生”功能时空演化过程及影响因素。[结果] ①2005—2018年山西省“三生”功能空间分异明显，生产、生活功能格局特征趋同，呈现出“平原高，山区低”的分布格局；生态功能分布特征与生产生活相反，空间格局稳定；“三生”综合功能提升明显，表现为“南高北低，中部高东西低”的局面。②2005—2018年生产和生态功能水平缓慢变化，呈现出先上升后下降波动变化趋势；生活功能处于快速提升阶段，提升明显；“三生”综合功能持续提高，但提升缓慢。“三生”功能协调性提高，但功能单一化程度较高。③“三生”功能时空分异是自然地理环境、自然资源禀赋及社会经济因素综合作用的结果，“三生”功能受制于自然地理条件，自然资源禀赋是“三生”功能的基础和保障，社会经济因素则是“三生”功能的主要驱动力。[结论] 山西省各县域需要在自然地理条件约束和经济社会转型发展背景下，促进“三生”功能各自提升与彼此协调，需要在明确各自主体功能定位的基础上，因地制宜，合理发展，依托自身区域优势与资源禀赋，构建起利益联结机制，推动山西省整体协调可持续发展。
[Objective] The temporal and spatial evolution and influencing factors of productional-living-ecological functions of Shanxi Province were analyzed in order to provide a basis for territorial and spatial planning.[Methods] Based on land use type data and statistical data of 107 counties in Shanxi Province in 2005, 2010, and 2018, the spatial and temporal differentiation pattern, evolution process, and influencing factors of the productional-living-ecological functions were determined by using a comprehensive index model, dynamic degree, and a spatial measurement model.[Results] ① The spatio-temporal differentiation feature of the productional-living-ecological functions was obvious in Shanxi Province from 2005 to 2018. The production function and living function were similar, showing a pattern of high in the plains and low in the mountains. The distribution of the ecological function was opposite to that of the production function and the living functions, and the spatial pattern was stable. The comprehensive productional-living-ecological functions improved dramatically, leading to a landform featured by higher in the south and middle, lower in the north, east, and west. ② The production and ecological functions changed slowly, showing a trend from 2005 to 2018 that first increased with time and then decreased. The living function was in a stage of rapid improvement, and it had improved significantly. The comprehensive functions of productional-living-ecological continued to improve, but it was in a stage of slow improvement. The coordination of functions of productional-living-ecological was improved, but the degree of functions simplification was higher. ③ The spatial and temporal differentiation of the productional-living-ecological functions was the combined effects of the natural geographic environment, natural resource endowments, and socio-economic factors. The productional-living-ecological functions were subject to natural geographical conditions. Natural resource endowment was the foundation and guarantee of the productional-living-ecological functions. Socio-economic factors were the main driving force of the productional-living-ecological functions.[Conclusion] All counties in Shanxi Province need to promote the respective enhancement and coordination of productional-living-ecological functions under the constraints of natural geographical conditions and economic and social transformation and development. On the basis of clarifying the positioning of their respective main functions, county planners need to adapt measures to local conditions, and develop measures rationally. Relying on their own regional advantages and endowment of resources, they could establish an interest linkage mechanism and promote the overall coordinated and sustainable development of Shanxi Province.
