Abstract:[Objective] The characteristics of territorial space in Fujian Province were explored, in order to solve the disorder of territorial space development caused by rapid urbanization and provide scientific basis for optimizing its layout. [Methods] Based on the perspective of production-living-ecological functions, taking Fujian Province as the research object, the comprehensive evaluation method, exploratory spatial data analysis, obstacle degree model and comparative advantage index analysis were used to evaluate the production-living-ecological functions, analyze its spatial distribution characteristics and obstacle factors, and figure out the superior function areas and put forward the optimizing countermeasures. [Results] ① The average values of production function, living function and ecological function of Fujian Province in 2018 were 0.061 8, 0.093 6 and 0.030 6, respectively. The spatial distribution characteristics of production-living-ecological functions in Fujian Province were higher in the east and lower in the west. ② The spatial distribution of the production-living-ecological functions were positively correlated. The spatial distribution characteristics of the hot spots and cold spots of the three were generally high in the east and low in the west, and there was a certain overlap in the region. ③ The main obstacles affecting production-living-ecological functions included economic density, total amount of ecological value service, traffic land density and urbanization rate. ④ The land space of Fujiang Province could be divided into four dominant functional areas. [Conclusion] There are great differences in production-living-ecological functions in Fujian Province, therefore, we should balance regional development and optimize the spatial layout of land.
