Promoting the intensive utilization of arable land is a critical strategy for addressing scarcity problem resources and thus ensuring food security. However, public emergencies pose significant challenges to land. Based on pressure-state response (PSR) model taking Sichuan Province, known as China’s “Heavenly Granary”, an example, this study constructs suitable evaluation system analyzes variation trend from perspective emergencies. Key factors constraining are further analyzed using obstacle diagnostic model. The findings follows: (1) Despite shocks emergencies, level in Province China shows overall upward trend, indicating high resilience adaptability. (2) pressure utilize intensively exhibits periodic fluctuations, yet state remains generally stable. whole positive adaptive responses external pressures contemporary conditions during mid-to-late stages research period. Nevertheless, coordination among subsystems within PSR framework suboptimal, dynamic equilibrium across has not been achieved. (3) Obstacle exhibit notable temporal variations. Early-period constraints centered multiple cropping indexes, grain yield per unit area, irrigation index, reflecting limitations traditional agricultural production modes. In later stages, key obstacles shifted including capita cultivated land, population density, pesticide/fertilizer input highlighting impediment effects caused by evolving socio-demographic dynamics influenced reveal pathways local governments achieve sustainable management amidst global uncertainties.
