【摘要】：为探讨交通承载力与环境承载力发展水平的协调程度,构建了反映交通承载力和环境承载力发展水平的指标体系,利用耦合协调度模型对2010—2014年中国五大国家级城市群中的10个典型城市的面板数据进行测算,并从时空维度进行二者耦合过程与演变趋势的分析.对比结果表明各城市群的交通和环境承载力综合评价值因地域差异较大,2010—2014年升降不一,具有层级结构:除长江中游和珠三角的交通承载水平呈波动下降趋势外,成渝、长三角和环渤海呈波动上升;除环渤海的环境承载力水平呈持续上升外,其余城市群呈波动下降;交通承载力与环境承载力耦合互动效应明显,但各城市群的交通与环境承载力的协调等级较低,环渤海和长三角城市群的协调处于低度协调的耦合状态,其余城市群的协调处于中度协调.
[Abstract]:In order to discuss the coordination degree between traffic carrying capacity and environmental bearing capacity, an index system reflecting the development level of traffic carrying capacity and environmental carrying capacity is constructed. By using the coupling coordination degree model, the panel data of 10 typical cities in five national-level urban clusters in China from 2010 to 2014 are calculated, and the coupling process and evolution trend of the two cities are analyzed from the space-time dimension. The results show that the comprehensive evaluation value of traffic and environmental carrying capacity of each city group is different from 2010 to 2014, and it has a hierarchical structure: except the traffic load level in the middle reaches of the Yangtze River and the Pearl River Delta is fluctuating and decreasing, Chengdu and Chongqing, The Yangtze River Delta and the Bohai Rim are fluctuating and rising; Except the environmental carrying capacity level of the Bohai Sea is rising continuously, the other urban groups are fluctuating and decreasing. The interaction effect of traffic carrying capacity and environmental bearing capacity is obvious, but the coordination level of traffic and environmental carrying capacity of each urban agglomeration is low, and the coordination of urban agglomeration around Bohai Sea and Yangtze River Delta is in the coupling state of low degree and coordination. The coordination of the remaining urban clusters is moderate.
