ABSTRACT The spatial heterogeneity of ecological vulnerability (EV) is a key indicator regional ecosystem differentiation. However, identifying the factors that contribute to this remains challenge in current research. This study proposed “Ecological vulnerability‐spatial heterogeneity‐zone” (ESHZ) framework as solution overcome difficulties monitoring heterogeneity. Then, based on typical river valley city Baoji Northwest China research object, was used analyze and predict evolution law EV from 2000 2030. findings indicate following: (1) Synthesized index (SEVI) 2020 2.47 2.49, respectively, with less than 5% total area transitioning areas higher EV, indicating relatively stable environment. (2) clustering characteristics remained stable, primarily showing non‐significant, high–high, low–low clustering, varying degrees across different regions. (3) Factors analysis revealed DEM LUCC had been dominant interactions between were stronger within them, suggesting its result combination factors. (4) CA‐Markov model predicted gradual improvement environment by 2030, Kappa coefficient test value 0.7733. constructed proposes perspective for improved analyses ecosystems, providing viable approach management vulnerability.
