Assessing the Trade-off between Ecological Conservation and Local Development in Wuyishan National Park: A Production–Living–Ecological Space Perspective

China’s national park establishment aims to achieve a balance between ecological conservation and regional development. This study adopts a production–living–ecological (PLE) space perspective to evaluate the park’s impact. By quantifying changes and employing a combination of geographic detector and coupling coordination degree analyses, this research explores the dynamics of habitat quality and PLE space within the Wuyishan region, alongside their interrelationships. The national park’s influence on the surrounding area exhibits spatial heterogeneity, evident both within and beyond park boundaries, as well as across different counties. Despite the concentration of PLE changes in the park’s vicinity, particularly in densely populated urban areas, the influence of the national park on the local area is random and primarily at a low level. Importantly, the ecological space exhibits substantial changes, mirroring improvements in habitat quality. Furthermore, the coupling coordination between habitat quality changes and PLE space changes exhibits remarkable spatial variations. The complex interrelationships among PLE space necessitate a coordinated approach to their development for effective national park management. Ultimately, this investigation provides a novel perspective for the assessment of Wuyishan National Park’s conservation effectiveness, contributing practical value for future endeavors.
