基于灰关联谱聚类模型的福建省暴雨灾害评价研究
Study on Evaluation of the Rainstorm Disaster in Fujian Province Based on Spectral Clustering Model with Grey Relational Analysis
摘要
Abstract
[Objective] The research aimed to study assessment index system of the rainstorm disaster in Fujian Province based on spectral clustering model with grey relational analysis. [ Method] According to meteorological disaster yearbook in Fujian Province,by comprehensively considering disaster-inducing factor, disaster-inducing environment, disaster-sustaining body and regional disaster-prevention level, evaluation index system of the regional rainstorm disaster in Fujian was established. By spectral clustering model based on grey relational analysis,risk zoning of the rainstorm disaster was conducted in each area of Fujian. Finally,effect and application of the clustering model were analyzed by instance research. [Result] In order to dig immanent connection among regional characteristics and improve disaster-preventing linkage performance of the evaluation unit,a spectral clustering model based on grey relational analysis was used to conduct risk zoning of the rainstorm disaster in Fujian Province. Moreover,combination weight was introduced to judge each evaluation index,so as to adjust clustering model. By case study,rainstorm disaster levels in 67 counties were obtained. Interior characteristics of each type were analyzed, and main relational factor of each type was extracted. It was compared with statistical result of the rainstorm disaster, verifying validity and feasibility of the model. [ Conclusion] The method was feasible,and its evaluated result had better differentiation and decision accuracy.关键词
