ABSTRACT
Urban expansion presents escalating challenges to ecological connectivity, while comprehensive research on long-term corridor conservation remains limited. This study integrates Omniscape with land-use scenario simulation to assess urbanization impacts on ecological networks in China’s Beijing-Tianjin-Hebei (BTH), Yangtze River Delta (YRD), and Pearl River Delta (PRD) regions. Key findings indicate: (1) By 2035, 41, 29, and 24 critical disruption points are projected for PRD, BTH, and YRD, respectively, requiring prioritized protection; (2) the expansion-loss ratio (corridor loss per urban growth unit) exhibits significant regional variation, with PRD (1.75) demonstrating ratios approximately 15% and 9% of those in YRD (11.56) and BTH (6.88); and (3) regionally tailored conservation strategies are essential due to distinct vulnerability patterns.
