LANDSLIDE RISK ASSESSMENT BASED ON COMBINED WEIGHTING AND CLOUD MODEL
To address the issues of low accuracy in assigning weights to landslide hazard evaluation indicators and the inability of comprehensive evaluation methods to account for indicator randomness and uncertainty,this study fo-cuses on landslide hazards in the Wenchuan—Lixian section,an improved analytic hierarchy process(AHP)and co-efficient of variation method are used to calculate both subjective and objective weights for the landslide hazard eval-uation indicators,additionally,a combined weighting approach is utilized to compute the composite weights of the in-dicators.Finally,a cloud model is employed for a comprehensive evaluation of landslide points and compared with other evaluation methods.The results indicate that the combined weighting-cloud model method more closely ap-proximates actual conditions,with 85%of the most likely landslide occurrences aligning with the real situation,this confirms that the proposed method is reasonable and feasible,providing valuable scientific guidance for landslide prevention and control in similar regions.
