Abstract: In order to reflect the present situation and coordination level of "production-living-ecological" function of geographical space in Yunnan province, an evaluation index system was constructed, and a comprehensive evaluation model was constructed by using entropy method. The coupling coordination degree model and coefficient of variation were used to analyze the functional coupling coordination characteristics of "production-living-ecological" function in Yunnan province from 2007 to 2017. The results showed that,"production-living-ecological" function was gradually strengthened, and the function of production and life showed a more obvious "center-periphery" structure. Because Dehong's foreign trade had developed rapidly in recent years, its production function was also more prominent; The ecological function was stronger than the production and life function, which was highe r in the west and lower in the east. The functional coupling coordination degree of "production-living-ecological" function gradually increased and the gap between cities decreased slightly, and the average annual growth rate of coupling coordination degree from 2007 to 2012 was higher than that from 2012 to 2017. The overall "production-living-ecological" function was in the stage of mild imbalance to primary coordination, and the spatial layout of coordination degree showed obvious characteristics of "center-periphery" structure and "overall imbalance and local equilibrium".

Key words: geographical space, "production-living-ecological" function, coupling coordination, spatio-temporal change, Yunnan province
