To explore the influence of land use change on landslide susceptibility, Liuyang City of Hunan Province was taken for research. An improved infinite slope model was established based on land use data from 2000 to 2020, by using an inversion model of root cohesion and dynamic hydrological correction, and the influence mechanism of land use change on landslide susceptibility was quantified. The model accuracy was verified by comparing six types of parameter combinations. It is found that the model considering spatial heterogeneity of root cohesion and saturated hydraulic conductivity corrected based on land use has extremely high prediction accuracy (AUC=0.815 0), presenting a significant improvement compared with the traditional model. Besides, forest land conversion to land for construction significantly increases landslide susceptibility (with a frequency ratio of 1.426 9), and decline of vegetation cover leads to reduction in root reinforcement.
