Constructing a rational ecological network is crucial for balancing regional development with environmental protection. However, existing research typically emphasizes the analysis of overall patterns, lacking an in-depth exploration dynamic changes in key elements and interactions between different components. Using Yongding River floodplain as case study, this study applied morphological spatial pattern analysis, landscape connectivity metrics, biodiversity assessments to identify core source areas. Circuit theory was used delineate corridors analyze evolution across four years, while graph facilitated structural characteristics. Furthermore, areas restoration were identified within floodplain. We found that number patches area has remained relatively stable, though their total shown fluctuating decline, accounting approximately 10% Additionally, have decreased significantly from 1967 2021, marked reduction major corridors, leading increased resistance material energy flow corresponding decline stability. More importantly, current pinch points are primarily distributed bead-like along channel, barriers concentrated northern eastern floodplain, often at intersections dense road networks corridors. These critical fragmentation prioritized targeted protection efforts. Overall, advances our understanding distribution composition river corridor offers framework evaluating these through multidimensional optimization approach patches. At same time, we conducted providing valuable guidance future initiatives
