With the drastic socioeconomic development, there is a pressing need for habitat-oriented cross-cutting solutions to address multiple challenges from different environmental dimensions, especially in urban agglomerations (UAs). This study put forward a research framework to evaluate the spatial interconnections and heterogeneities between various environmental indices and residential habitat quality from multi-perspective profiling. We integrated cartographic comparison, correlation analysis, local entropy model, and GeoDetector, comparing the three largest Chinese UAs, namely Beijing-Tianjin-Hebei (BTH), Greater Bay Area (GBA), and Yangtze River Delta (YRD).
The analysis showed solid spatial relationships between habitat quality and multifaceted environmental situations for the three UAs. Most regional landscapes in the three UAs displayed low-medium habitat quality, intersecting with severe consequences from thermal, air, living, and biological spheres. Overall, habitat quality in the three UAs was positively related to NDVI but negatively associated with surface heat island intensity, air pollution, and residential support. The local entropy maps highlighted spatial diversities and complex patterns of significant local heterogeneities and guided the analysis to focus on specific regions. The interaction of different environmental issues in the three UAs mutually affected the habitats, illustrating the compound environmental risks and the need for prioritizing decision-making processes. The findings of this study support the multi-dimensional sustainability and co-benefits sought by taking advantage of the relationships and interactions between habitats and diverse environmental issues in the UAs.
