Abstract

Abstract:

Urbanization significantly alters land use and land cover, with consequence on ecosystem services. While previous studies have predominantly focused on individual cities or small-scale regions, the spatial interactions between urbanization and ecosystem services in urban agglomerations remains less understood. We used spatial autoregressive models to assess the spatial interaction between urbanization and ecosystem services in the Beijing-Tianjin-Hebei (BTH) urban agglomeration from 2000 to 2020. We found that urbanization indicators in the BTH region, including urban proportion, population density, and GDP density, exhibited an upward trend. They shared the similar spatial distribution patterns. Different ecosystem services showed differentiated variations. Food supply increased significantly across the urban agglomeration, while carbon storage and habitat quality declined in most areas, except for the ecological conservation zone in the northwest. Carbon storage and habitat quality were negatively correlated with the comprehensive urbanization index. Urban land expansion was directly associated with the degradation of ecosystem services, while population and economic growth exerted indirect influences. This study provides valuable insights for promoting sustainable and coordinated development, as well as high-quality spatial development in the BTH region.
