Abstract

The construction of an ecologically livable city has emerged as a crucial objective in Guangzhou's “14th Five-Year Plan” and the vision for 2035. This paper establishes an evaluation index system for urban ecological livability, encompassing five dimensions: economy, society, technology, environment, and nature. It employs the TOPSIS analysis method and a coupling coordination model to conduct a trend analysis of the evaluation values and coupling coordination degrees of these five systems in Guangzhou from 2014 to 2023. The findings indicate: (1) the overall ecological livability of Guangzhou shows a positive trend, with a relatively favorable development level; however, the progress of each system is constrained by various factors. (2) Since 2015, the coupling degree of the five systems has gradually increased, maintaining a good state since 2017. The calculations of coordination degree reveal a steady rise in the overall system's coupling coordination. This study enhances the index system for ecologically livable cities and offers policy recommendations to strengthen urban ecological livability, thereby providing valuable guidance for promoting sustainable urban development and the construction of ecologically livable cities.
