Abstract

Reviewing the coupling coordination between urban ecological resilience (UER) and new-type urbanization (NU) has gradually become a necessary condition for understanding the structure and service patterns of urban ecological systems. Discussion on the temporal and spatial coordination evolution in UER and NU in urban agglomerations with different characteristics is beneficial for understanding the operational mechanisms of urban ecosystems. This work constructs a novel evaluation framework for the coupling coordination process between UER and NU, and scientifically measures the performance of each indicator using the entropy method and CRITIC method. By using the coupling coordination degree (CCD) model, this paper explores the spatio-temporal effects of the relationship between UER and NU, which has narrowed the cognitive gap. Using the Chengdu-Chongqing Economic Circle in China as an example, the validity and practicality of the framework are verified. The results show that the CCD between UER and NU generally shows a rapid growth trend with time and tends to be balanced; and the development patterns of CCD in urban agglomerations show significant spatial differences influenced by factors such as location advantage, natural resources, and human social activities. These results and findings can provide decision-making information reference for urban ecological system services, urban livability, and government planning.
城市生态弹性与新型城镇化的耦合协调研究——以成渝经济圈为例
研究城市生态弹性与新型城镇化之间的耦合协调性已逐渐成为认识城市生态系统结构和服务模式的必要条件。探讨不同特征城市群UER和NU的时空协调演化,有助于理解城市生态系统的运行机制。本文构建了一种新型的UER与NU耦合协调过程评价框架,并采用熵值法和CRITIC法对各指标的绩效进行了科学的度量。本文利用耦合协调度(CCD)模型,探讨了在缩小认知差距的过程中,UER与NU关系的时空效应。以中国成渝经济圈为例,验证了该框架的有效性和实用性。结果表明:UER与NU之间的CCD总体上随时间呈快速增长趋势,趋于平衡;受区位优势、自然资源和人类社会活动等因素的影响,城市群CCD的发展格局呈现出显著的空间差异。研究结果可为城市生态系统服务、城市宜居性和政府规划提供决策信息参考。
