ABSTRACT Effectively quantifying plantation forest fragmentation is crucial for vegetation restoration and management on the Loess Plateau. Forest area density (FAD) effectively measures fragmentation, with multiscale sensitivity analysis essential determining appropriate window scale threshold. This study uses data from different geomorphological types (hilly gully plateau region) of Various sizes are applied to evaluate FAD threshold curve its derivative a stable threshold, while structural equation model employed analyze drivers fragmentation. The results as follows: (1) variability decreases increasing size, leveling off after reaching (2) Thresholds vary by type county. (3) Two principal components explain 81.27% stabilization variation, strong correlations between similar types. (4) Fragmentation slowed 2000 2022, hilly region more fragmented than region. (5) Stand structure mitigates topographic climate change influences showing heterogeneity. “Core” maintain stability, “Islet” drive emphasizes importance scale‐specific adaptive strategies in mitigating supports optimizing ecological targeted conservation strategies, promoting sustainable
