| Abstract: | In order to achieve efficient risk assessment and potential geologic hazard management,the hazard susceptibility index,the amount of population and infrastructure threaten by hazard are chosen as evaluating indicators to calculate the risk grades of the potential landslides in Luogang District by using the DEA-CCR model,and the relative importance values of risk are arranged and classified.The reasonableness of the results is tested.It is shown that the DEA-CCR model is useful in risk assessment of the pote... |
