The rapid development of urbanization has led to population growth, increased resource consumption, and intensified environmental pollution. Consequently, urban ecological security increasingly become a key factor constraining the sustainable socio-economic systems. This study constructed an evaluation system based on Pressure-State-Response (PSR) model used Xuzhou, typical coal city, as case apply validate model. Specifically, analytic hierarchy process entropy weight method were determine index weights, was evaluate status each in Xuzhou from 2006 2022. Finally, grey prediction GM (1,1) predict next five years. results show that “disposal capacity waste gas treatment facilities”, “per capita disposable income”, “agricultural fertilizer application intensity” occupy large whole system. pressure generally showed fluctuating upward trend, state fluctuated around 0.12. There is simultaneous trend response composite index. level “unsafe” “relatively safe” 2022 will continue improve “ideal security” future. provides scientific basis for formulation policies also reference safety management assessment other similar cities.
