[Objective] The aims of this study are to understand the level of energy consumption and urban ecology-development system coordination in Yunnan Province, so as to effectively provide a certain research basis and scientific reference for optimizing urban development and reasonable resource allocation in Yunnan Province. [Methods] Based on 2013—2019 light NPP/ⅦRS data of night and socio-economic statistics in the study area, the correlation between light data and energy consumption was established, and the coupling coordination degree model was used to analyze the spatiotemporal characteristics of energy consumption levels and urban ecological development system coupling coordination in Yunnan Province in 2013—2019. [Results](1)With the development in 2013—2019, the overall energy consumption level of Yunnan Province and the coordinated development of urban ecology development coupling showed a slow upward trend, with an increase of 44.51% in 2013—2015, 4.8% in 2015—2019, and the growth slowed decline.(2)The eastern cities with Kunming as the center entered the stage of coordinated development earlier, and the coupling coordination index of most other states and cities was between 0.2~0.5, with a low level of coupling coordination.(3)The degree of coupling and coordination of urban agglomeration in central Yunnan is the highest. The cities in northwest and northeast Yunnan had been in an imbalance stage for a long time. The overall development of Yunnan Province was still unbalanced, and there was still a lot of space for coupling and coordinated development.(4)The change of energy consumption level and comprehensive evaluation index of development in each region had a great impact on the coupling coordination degree. There were differences in regional response. The energy consumption level interacted and restricted with the urban ecology and development system. [Conclusion] The energy consumption level of Yunnan Province is closely related to regional development, so the observation and research of urban coordinated development should be strengthened in the future.
