In the process of ecological civilization construction, it is unclear whether regional development can realize the coordination of production-living-ecological space (PLES). Based on the evaluation of PLES in the urban agglomeration of the Fujian Delta region of China, a functional index (PLESI) was established to examine spatial disparities, differences of functional levels, and driving mechanisms behind changes over a recent 15-year period. The results showed that during 2000-2015, the production and living space in the urban agglomeration of the Fujian Delta region was concentrated in the eastern coastal areas with an expanding trend over time, while the ecological space was concentrated in mountainous and hilly areas with a shrinking trend. At the same time, the functional level of PLES in the urban agglomeration of the Fujian Delta had a certain spatial agglomeration, which appeared to be decreasing overall over time. As for PLESI, the core-periphery boundary of the urban agglomeration of Fujian Delta was roughly divided into an eastern zone with a lower functional level and a western and southern zone with a higher functional level. Finally, the PLES in the urban agglomeration of the Fujian Delta has poor coordination, and its cooperation-competition and conflict were mainly caused by natural and human factors. This study aimed to provide a prejudgment basis for the future evolution of cooperation-competition of production-living-ecological space in the urban agglomeration of Fujian Delta, as well as a reference for decisions to promote the coordinated development of production-living-ecological space.
