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.
To discuss the coordination development of traffic carrying capacity（TCC）and environment carrying capacity（ECC）,a coupling harmonious degree model and an index system are established.Applying coupling coordination model to 2010—2014panel data of ten typical cities from five National Urban Agglomeration,this paper analyzes the coordination development of the traffic carrying capacity and environment carrying capacity on the prospect of space-time dimensions.It is found that the synthetical values of each urban agglomeration differs greatly because of regional differences,forming a hierarchy structure ranging rise and fall from 2010 to 2014.The level of TCC of Middle Reaches of the Yangtze River（MRYR）and Cheng-Yu Town Cluster（CYTC）is obviously higher than the other three,while the Bohai Ring megalopolis owned the lowest values.The level of ECC of Pearl River delta is the highest,and the second is MRYR,lastlythe CYTC and Yangtze River delta.The coupling degrees of each urban agglomeration between traffic carrying capacity and environmental carrying capacity appear high yet the coordination degrees appear low,unfortunately,the coordination degrees of all five urban agglomerations are at low coordination coupling stage,tending to be undergoing serious inharmonious.
