Amid ongoing climate warming and rapid urbanization, arid and semi-arid ecosystems face heightened threats and degradation. This study highlights the urgent need to construct ecological security pattern (ESP) that preserves critical ecosystem functions and strengthen ecological security in Northwest China. We integrated ecological security assessments—utilizing the Ecological Risk Index (ERI), Ecosystem Health (EH), and Comprehensive Ecosystem Services Index (CESI)—with advanced analytical techniques, including Morphological Spatial Pattern Analysis (MSPA), the entropy weight method, Minimum Cumulative Resistance (MCR), and the Gravity Model (GM). Our analysis spanned the period from 1990 to 2020, enabling the construction and optimization of ESPs for the region. Additionally, we employed Partial Least Squares Structural Equation Modeling (PLS-SEM) and Geographically and Temporally Weighted Regression (GTWR) to analyze the driving factors and pathways that influence ecological security. Key findings reveal that: (1) Ecological security zones are predominantly concentrated in the southeastern part of the study area, while ecological mitigation zones are distributed in southern Xinjiang and central Qinghai. These areas, particularly around the Tarim, Turpan–Hami, and Qaidam Basins, represent critical regions for ecological restoration due to their vulnerability to desertification and habitat degradation; (2) Northwest China demonstrates a unique ecological development framework...
