Comprehensive zoning study based on the identification of spatial conflicts and ecosystem service values–a case study of urban agglomeration around Poyang Lake, China

This study, focusing on landscape patterns, established a spatial conflict metric model to recognize the temporal and spatial evolution of conflict intensity in urban agglomeration. It further evaluated the value of ecosystem services through the equivalent factor method. Utilizing spatial autocorrelation, the study area was zoned, and tailored development recommendations were proposed based on the characteristics of each zone. The results show that: (1) The spatial conflict intensity of the urban agglomeration around Poyang Lake shows an upward trend and obvious spatial differentiation. Specifically, the low-conflict zones mainly concentrated in the western and eastern mountainous areas of the study area with block distribution, while the high-conflict zones are dispersed in the urban core area. (2) Between 1990 and 2020, the ecosystem service value of the study area showed an increasing trend, with woodland contributing the most. Western, northeastern, and southeastern regions boast high service values, contrasting with the low values in the metropolitan agglomeration and its periphery. (3) A negative spatial correlation was observed between spatial conflicts and ecosystem service values, with the correlation gradually intensifying from 1990 to 2020.
