A Comprehensive Evaluation Method for Geological Hazard Management Based on Entropy Weight Method
How to scientifically evaluate the prevention and control effects of geological disaster management projects has always been a difficult point in disaster prevention and reduction work in various regions.This article combines a landslide engineering example and establishes a comprehensive evaluation system for the prevention and control effects of various participating parties(survey units,design units,construction units,supervision units,and construction units)in the project.A total of 26 secondary factor indicators are set up,and the weight of each factor indicator is determined using the entropy method,According to the multi factor weighted index and legal quantity,the grading score and comprehensive score are calculated,and the reliability of the scoring data is tested using SPSS software.After verification,the evaluation system has strong operability,the evaluation results are true and reliable,consistent with reality,and can provide a certain basis for government management departments to supervise and manage participating units.
