摘要
运用综合空气质量指数法、综合集成赋权法、耦合协调度模型、空间自相关等方法对京津冀城市群2008—2016年间城镇化与空气环境耦合协调关系进行定量测度,并对其空间分布特征进行分析。结果表明:(1)京津冀城市群城镇化指数不断上涨,空气环境综合指数呈“N”型变化趋势;(2)城镇化—空气环境的耦合协调度波动式上涨,整体处于不协调发展状态;(3)城镇化—空气环境的耦合协调度存在高值集聚的空间特征,基本形成以北京—天津为核心的协调热点区。
The quantitative measurement and spatial characteristics of coupling and coordination relationship between urbanization and air environment in Beijing-Tianjin-Hebei urban agglomeration from2008 to 2016 are analyzed by using comprehensive weight metho d,coupling coordination degree model and spatial autocorrelation method.Results show that:①The urbanization index of Beijing-Tianjin-Hebei urban agglomeration shows a rising trend,and the comprehensive level index of air environment shows an "N" development trend;②The degree of coupling and coordination between urbanization and air environment fluctuates,and comprehensive degree is in a state of uncoordinated development;③The coupling and coordination degree of urbanization and air environment has significant spatial characteristics of high-value agglomeration,which basically forms a coordination hotspot area with Beijing and Tianjin as the core.
