Boosting algorithms have been widely utilized in the development of landslide susceptibility mapping (LSM) studies. However, these possess distinct computational strategies and hyperparameters, making it challenging to propose an ideal LSM model. To investigate impact different boosting hyperparameter optimization on LSM, this study constructed a geospatial database comprising 12 conditioning factors, such as elevation, stratum, annual average rainfall. The XGBoost (XGB), LightGBM (LGBM), CatBoost (CB) were employed construct Furthermore, Bayesian (BO), particle swarm (PSO), Hyperband (HO) applied optimizing exhibited varying performances, with CB demonstrating highest precision, followed by LGBM, XGB showing poorer precision. Additionally, displayed HO outperforming PSO BO performance. HO-CB model achieved boasting accuracy 0.764, F1-score 0.777, area under curve (AUC) value 0.837 for training set, AUC 0.863 test set. was interpreted using SHapley Additive exPlanations (SHAP), revealing that slope, curvature, topographic wetness index (TWI), degree relief, elevation significantly influenced landslides area. This offers scientific reference disaster prevention research. examines utilization various Wanzhou District. It proposes HO-CB-SHAP framework effective approach accurately forecast disasters interpret models. limitations exist concerning generalizability data processing, which require further exploration subsequent

Abstract As the global push for sustainable urban development progresses, this study, set against backdrop of Hangzhou City, one China’s megacities, addressed conflict between expansion and occurrence geological hazards. Focusing on predominant hazards troubling Hangzhou—urban road collapse, land subsidence, karst collapse—we introduced a Categorical Boosting-SHapley Additive exPlanations (CatBoost-SHAP) model. This model not only demonstrates strong performance in predicting selected typical hazards, with area under curve (AUC) values reaching 0.92, 0.94, respectively, but also, through incorporation explainable SHAP, visually presents prediction process, interrelations evaluation factors, weight each factor. Additionally, study undertook multi-hazard evaluation, producing susceptibility zoning map multiple while performing tailored analysis by integrating economic population density factors Hangzhou. research enables decision makers to transcend “black box” limitations machine learning, facilitating informed making strategic resource allocation scheduling based demographic area. approach holds potential offer valuable insights cities worldwide.
