Abstract
To lay the foundation for disaster prevention and control in small watersheds,this study established an evaluation model for disaster proneness degree in small watersheds using the Analytic Hierarchy Process(AHP),CRITIC method(Criteria Importance Through Intercriteria Correlation),and expert evaluation approach,based on the analysis of basic characteristics and calculation of characteristic parameters.The model quantitatively determined the disaster proneness grade.The analysis results show that a certain small watershed is large in scale with obvious zonal characteristics,significant disaster development,and an overall disaster proneness score of 81.39,belonging to Grade III of disaster proneness,featuring relatively high disaster susceptibility,indicating that the disaster proneness degree of the small watershed is very high.Therefore,prevention and control measures should be implemented as soon as possible.Through this research,we not only grasped the formation conditions and basic characteristic parameters of a certain small watershed,but also quantitatively evaluated its disaster proneness degree,laying a foundation for subsequent prevention and control measures.This study also accumulates valuable experience for similar research,demonstrating practical significance.关键词
