京津冀区域绿色发展与城市化的耦合协调发展研究

Research on Coupling Degree of Green Development and Urbanization in Beijing-Tianjin-Hebei Region

结合绿色发展与城市化内涵,通过构建两者的耦合度模型,对“十二五”时期京津冀区域绿色发展与城市化的协调发展状况进行了研究,研究结果表明:绿色发展中各项指标贡献度相对均衡,但城市化水平中经济城市化贡献度最高;绿色发展综合指数均呈现出上升趋势但区域间梯度明显,城市化水平综合指数京津较高、河北最低;绿色发展与城市化水平耦合协调程度均表现出阶段性特征,但区域间差距明显。

Based on the concepts of green development and urbanization, this paper builds the coupling degree model (CDM) to research on the green development and urbanization in Beijing- Tianjin-Hebei region during the 12 th Five-Year Plan. The results shows that: The contribution degree in index of green development strikes a balance relatively while the economic urbanization contributes the most in all process of urbanization. The composite index of green development presents upward trend but the gap between different regions is obvious. Comparing with Beijing and Tianjin which lie in higher level in composite index of urbanization, Hebei province ranks the worst level. The coupling degree of green development and urbanization has taken on periodic features and obvious regional disparity.
