Research on the joint evaluation of geological disaster susceptibility based on fractal theory and hierarchical analysis method

HIGHLIGHTS

• What: With the development of the research, the heuristic inference method is simple but subjectively biased; although the statistical method is objective, it is difficult to distinguish the differences between the attribute factors; and the nonlinear method has high accuracy, but the calculation process is too complicated. The verification results showed that the AUC value obtained through the joint model was 0.865, and the historical disaster spot density in very high and high prone areas was high and the occupation area was small, indicating that the joint model met the accuracy requirements of regional geological disaster . . .
