摘要

As global environmental challenges intensify, regions worldwide are pursuing strategies for ecological governance and sustainable social development. The coordinated development of the transport-ecology-population triad has emerged as a pivotal focus in sustainability research. This study employs the Pressure-State-Response (PSR) and Coupling Coordination models to analyse the coordinated development of Guangdong Province’s transport, ecological, and population systems from 2008 to 2021, examining indicator interdependencies and coordination mechanisms. Findings reveal that the transport pressure system exhibits sustained growth, while the ecological state system shows improvement yet fails to advance synchronously. The population response system undergoes continuous transformation against an urbanisation backdrop. Through PSR model validation, this study uncovers complex indicator relationships among the three systems and their evolutionary coordination processes. This theoretical framework not only enhances the robustness of results but also provides policymakers with theoretical insights to advance coordinated development in transport infrastructure, ecological conservation, and population structure optimisation. This research offers a unique theoretical contribution to evaluating the coordinated coupling of the three systems, further validating the effectiveness and influence relationships of the transport-ecology-population indicator system through the PSR model.
