Abstract: As a core growth pole in the middle reaches of the Yangtze River,the urban agglomeration region around Changsha-Zhuzhou-Xiangtan faces acute contradictions between ecological protection and economic development amid rapid urbanization.Clarifying the spatiotemporal evolution patterns and influencing factors of its ecosystem service value (ESV) is crucial for coordinating regional sustainable development.At the county scale,we integrated regional differentiation coefficients,biomass factors,and social development coefficients to refine the ESV assessment model,quantifying spatiotemporal dynamics from 2005 to 2023.Using geographical detectors,we analyzed the impacts of natural environment, socio-economic factors, and spatial location factors,revealing that:(1) Total ESV exhibited continuous decline,spatially presenting a "high-east-west,low-center" pattern,with high-value areas concentrated in ecological barrier zones like Xuefeng and Mufu Mountains,and low-value areas in the urban cores.(2) Human activity intensity (HAI),population density,and primary industry GDP ranked as the top three ESV drivers,while annual temperature and slope showed significant individual effects.All factor interactions demonstrated either two-factor enhancement or nonlinear enhancement,particularly the synergistic effects among HAI,road density,and temperature,revealing coupled amplification mechanisms between human activities and natural backgrounds.(3) Ostrom's social-ecological system framework analysis indicated policy-economic interactions primarily drove ESV decline through HAI and road network expansion,with natural backgrounds modulating their intensities.Accordingly,we propose establishing a "green heart-water-mountain" ecological network with strict construction land control in core areas,developing cross-regional ecological compensation mechanisms based on ESV increments,and promoting green industrial transformation to mitigate eco-economic imbalances.

Key words: ecosystem services, human activities, influencing factors, spatial heterogeneity, the urban agglomeration region around Changsha-Zhuzhou-Xiangtan
