- [目的]了解云南省能耗水平与城市生态-发展系统间的协调程度,以便有效地为云南省优化城市发展以及合理资源分配提供一定的研究基础与科学参考。[方法]基于研究区2013—2019年夜间灯光NPP/ⅦRS数据与社会经济统计数据,建立灯光数据与能源消耗量间的相关性,并运用耦合协调度模型分析了2013—2019年云南省各州市能耗水平和城市生态-发展系统耦合协调时空特征。[结果](1)随着2013—2019年发展,云南省整体能耗水平与城市生态-发展耦合协调发展状况总体呈缓慢上升趋势,2013—2015年增长了44.51%,2015—2019年增长了4.8%,增幅有所放缓;(2)以昆明为中心的东部城市更早进入协调发展阶段,其余大部分州市耦合协调指数为0.2～0.5,耦合协调水平较低;(3)滇中城市群的耦合协调程度最高,滇西北和滇东北城市长期处于失调阶段,云南省整体上发展仍不平衡,耦合协调发展仍有很大空间;(4)各地区能耗水平与发展综合评价指数变化对耦合协调度影响较大,存在地区响应的差异,能耗水平与城市生态及发展系统间是相互作用与制约的。[结论]云南省能耗水平与地区发展密切相关,未来应加强城市协调发展的观测研究。
- Abstract:
- [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.
