The “West-to-East Gas Transmission” project has accelerated economic development in Xinjiang and the central-western regions along pipeline. However, as pipeline traverses multiple cities counties Tianshan region, it significantly impacted local ecology, necessitating a comprehensive assessment. This study employs Sensitivity-Resilience-Pressure (SRP) model to construct an ecological vulnerability assessment system for aiming analyze changes evaluate environmental impact of project. results indicate that, spatially, region increases progressively from northwest southeast. Temporally, 2000 2010, mean Ecological Vulnerability Index (EVI) exhibited decreasing trend, with values 0.476, 0.464, 0.462, primarily shifting lower levels. From 2010 2020, EVI showed increasing 0.466, 0.468, predominantly transitioning heavy very vulnerability. key influencing factors ranked by importance, are NDVI, NPP, land use type, annual precipitation, aridity. Furthermore, consists three main pipelines (Lines 1, 2, 3), which buffer zone analyses were conducted at radii 1 km, 3 5 km. that patterns remained consistent across different sizes, larger associated After construction, Line decreased 0.566 0.550, while 2 nearly unchanged. In contrast, increased 0.434 0.447. Regarding levels, area improvement (18.83%) exceeded deterioration (1.09%), due high proportion zones (>80%), more likely transition Along relatively stable, indicating minimal impact. 3, (3.81%) was smaller than (20.52%), suggesting construction had pronounced impact, leading greater degradation its route.
