Abstract Urbanization has surged over the past decades. Global major cities’ land urbanization and population have intensifying pressures on urban climate, public health, energy consumption. A favorable vision for assessing habitats’ living conditions necessitates recognizing evolution current status of global three-dimensional structure spatiotemporal trajectories. However, a lack high-resolution, long-term data hinders obtaining metrics reflecting conditions. This study addresses this gap by generating 30-meter resolution expansion dataset 2071 cities (1990–2020). Integrated with socioeconomic data, it reveals adherence to Zipf's Law, pronounced unequal development global-scale Matthew effect.

Landscape fragmentation accompanied by weakened urban-rural ecological connections and even isolation. However, traditional networks (EN) construction has failed to address the isolation, as it overlooks variations in elements along gradients. Here, we proposed an innovative extraction strategy that combined morphological spatial pattern analysis (MSPA) minimal area threshold (MAT) method for differentially of sources. Different distance thresholds were established build multi-species network through minimum cumulative resistance (MCR) model, then optimized graph theory circuit theory. The results included: (1) 133 sources extracted, with a predominant concentration south north rural regions, while appearing scattered suburban urban areas. Ecological corridors comprising urban, urban-rural, corridors. final complemented previous neglect highly urbanized (2) Urban-rural segregation was more significant short-distance migrating species. After optimizing, improved at different dispersal distances. (3) Differentiated protection strategies forming "two cores, six pieces, five straps" pattern, emphasized key protection, priority restoration, enhancement. This paper could strengthen linkages guide conservation policy megacities.
