| description | The invention provides a landslide susceptibility assessment method introducing land utilization dynamic change. The method comprises the following steps: 1, primarily selecting landslide evaluation factors, and constructing a landslide susceptibility evaluation factor database; 2, dynamic factors and land utilization change analysis are introduced, and the correlation between land utilization change and landslide development is quantitatively measured through the landslide frequency ratio; 3, constructing a frequency ratio model based on evaluation factors except land utilization, and determining a preliminary susceptibility partition; the same number of landslide negative samples are randomly extracted from the extremely low susceptible area of the frequency ratio model to form a machine learning data set, and model prediction effects before and after land utilization change factors are introduced are compared and analyzed by adopting LR; constructing a DT model, a GBDT model and an RF model, and performing |
