The evaluation of systemic sensitivity and landscape vulnerability holds significant implications for regional management and sustainable development. Taking the Heisha River waste-shoal land system in Liangshan Yi Autonomous Prefecture, Sichuan Province, as the research object, this research analyzed the characteristics of land-use change of 2014, 2018, 2022 based on historical remote sensing data. Considering socio-ecological factors, the relationship between the spatial and temporal distribution pattern of systemic sensitivity and landscape vulnerability and its driving factors were evaluated by analytic hierarchy process and entropy weight method, Geodetector, spatial autocorrelation and other methods. The results showed that, the land use types of the study area were mainly cultivated land and forest land, and the overall trend showed a decrease in cultivated land and an increase in forest land and construction land. Systemic sensitivity showed a decreasing trend over time and a spatial pattern of being lower in the west and higher in the east, exhibiting a spatial positive correlation of high-high clustering and low-low clustering. Geographical detector analysis revealed that annual average rainfall, elevation, annual average temperature, and distance from fault zones are the main driving factors of Systemic sensitivity, with the interaction of natural and anthropogenic factors exacerbating the changes in systemic sensitivity.Furthermore, landscape vulnerability showed an increasing trend followed by a decrease over time, with a spatial distribution characteristic of being higher in the west and lower in the east, which is mismatched with the spatial distribution of systemic sensitivity. The findings of this study can aid in optimizing disaster prevention and mitigation strategies and regional development policies.
