Multi-scale differences in landscape connectivity evaluation and protection strategies: a case study of Chongqing, China.

ABSTRACT: Against the backdrop of rapid urban expansion, preserving landscape connectivity has become a vital approach to addressing habitat fragmentation and enhancing biodiversity. This study takes Chongqing, China, as a case study and establishes a multi-scale evaluation framework encompassing the Main urban area-Main metropolitan area-Chongqing city. Using landscape connectivity indices and ecological security patterns, the study evaluates the structural and functional connectivity of the research area. Through comparative analysis, it demonstrates the scale-dependent differences in regional landscape connectivity and proposes protection strategies from a multi-scale perspective. The results indicate that in terms of structural connectivity, as the study scale expands, the dPC (Delta Probability
