Abstract: Abstract Urban expansion in the Yangtze River Basin has profoundly altered landscapes, posing considerable challenges to natural conservation and socioeconomic sustainability. Understanding the scale of urban expansion at the subbasin scale and implications for ecosystem services is crucial for sustainable development and regional environment protection. This study examined the relationships between subbasin-scale urbanization and ecosystem services from 2000 to 2020 using the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) model, Multi-scale Geographically Weighted Regression (MGWR), and the Spatial Durbin Model (SDM). The results indicated a continuous acceleration of urbanization, leading to a decline in key ecosystem services, including Water Yield (WY), Soil Conservation (SC), Carbon Storage (CS), and Habitat Quality (HQ). Notably, WY remained relatively high in the coastal areas of the Poyang Lake Basin, while SC was higher in the Jialing River Basin. Ecosystem services between regions showed spillover effects, forming a 'clustering effect' on ecosystem services. However, urban expansion primarily affected local ecosystem services, possibly due to factors such as urban management boundaries. These findings provide new insights into eco-environmental management, emphasizing the need for integrated strategies that balance urbanization with the natural protection and resource regulation in the Yangtze River Basin.
