Abstract:

To assess the spatiotemporal dynamics of habitat quality and its drivers in the Capital Economic Zone (CEZ) from 1990 to 2020, we integrated multi-source, heterogeneous remote sensing data and biophysical models to evaluate habitat quality trends. Spatial autocorrelation analysis revealed distinct spatial clustering patterns, while a spatiotemporal geographically weighted regression (GTWR) model quantified the temporally and spatially heterogeneous impacts of natural, socio-economic, and landscape configuration factors. Key results indicate: (1) Habitat quality distribution strongly correlates with land-use types, with forests exhibiting the highest quality and built-up/agricultural lands the lowest. Despite relative spatial stability, the CEZ experienced a 3.51% mean decline in habitat quality, concentrated in rapidly urbanizing Tianjin (-23%) and Langfang (-21%); (2) Habitat quality displayed persistent positive spatial autocorrelation (Moran’s I), with high-high clusters in northwestern districts (ecologically stable zones) and low-low clusters in southeastern districts (urban/agricultural cores), consistent with regional urbanization gradients; (3) Driver impacts diverged spatiotemporally: precipitation, NDVI (vegetation cover), elevation, and landscape connectivity metrics (NP, PD, IJI, SPLIT) enhanced habitat quality, whereas temperature, GDP, population density, and fragmentation indices (SHAPE, PARA_MN, PRD, SHDI) degraded it. Patch cohesion (COHESION) exhibited spatially balanced positive/negative effects. This work provides a mechanistic framework to disentangle urbanization-ecology trade-offs, supporting spatially targeted policies for sustainable development in metropolitan regions.
