The invention discloses an area landslide hazard risk assessment method. The method includes the steps that at least one disaster pregnancy factor and at least one disaster causing factor for at least one landslide disaster point in an interesting area are obtained from different data sources; a landslide disaster sensibility index is calculated based on the disaster pregnancy factor; a landslide disaster dangerousness index is calculated based on the landslide disaster sensibility index and the disaster causing factor; at least one disaster bearing body vulnerability assessment factor is obtained, and a landslide disaster vulnerability index is calculated based on the disaster bearing body vulnerability assessment factor; a landslide disaster risk index is calculated based on the landslide disaster dangerousness index and the landslide disaster vulnerability index; landslide disaster risks are assessed according to the calculated landslide disaster risk index.
