Exploring the Relationship between Land Use Conflict and Ecosystem Services across Counties in the Poyang Lake Urban Agglomeration
摘要
Abstract
To reveal the spatiotemporal relationship between land use conflict and ecosystem services in the urban agglomeration around Poyang Lake,six periods of land use data(2000,2005,2010,2015,2020,and 2023)were used.A land use conflict measure-ment model,the InVEST model,bivariate spatial autocorrelation analysis,and the breakpoint regression method were comprehensively applied to systematically analyze the spatiotemporal evolution characteristics and threshold effects of land use conflict,ecosystem ser-vices,and their coupling relationship at the county scale.The results showed that:(1)From 2000 to 2023,the land use conflicts in the study area exhibited a spatial pattern of"high in the central region and low in the peripheral areas",with a temporal trend of first in-creasing and then decreasing,forming an inverted"V"shape.This change was mainly reflected in the decreased land use complexity and vulnerability indices,and an increased stability index.(2)The ecosystem service comprehensive index(ESCI)presented a spatial pattern of"high in the east and low in the west",with a fluctuating upward trend over time.Among the services,water yield(WY)and food provision(FP)had shown fluctuating upward trends,while habitat quality(HQ)had been continuously declining.(3)A significant negative correlation was observed between land use conflict and ecosystem services.The LISA clustering results were primarily charac-terized by low-high clusters.Moreover,the relationship between the two exhibited a clear nonlinear threshold characteristic:once the conflict exceeded the threshold,the degradation risk of ecosystem services accelerated significantly.In conclusion,the findings can provide a scientific basis for optimizing zoning regulation strategies and promoting sustainable development in the urban agglomeration around Poyang Lake.关键词
