Unsustainable human activities threaten the ecological security of arid and semi-arid watersheds. However, improving connectivity networks can enhance ecosystem services preserve biodiversity in these fragile environments. In this study, we aimed to identify sources Tabu River Basin by quantifying five key using a morphological spatial pattern analysis model. We further optimized resistance surfaces landscape indices, constructed an network, provided recommendations for sustainable management. The results obtained were as follows: (1) Ecosystem exhibit clear heterogeneity, with significant increases water yield, food supply, carbon sequestration over past two decades. (2) Landscape such aggregation index, patch cohesion Shannon’s diversity showed declines, indicating heightened fragmentation reduced connectivity. (3) Over study period, number increased from 6 17, although total area decreased. corridors expanded 9 36, length increase 362.47 km, whereas pinch points 27 40. (4) After optimization, one additional corridor 24 new identified, alongside marked reduction northern central-western regions. These provide robust scientific basis optimizing land-use planning reinforcing Basin.
