Lightning Disaster Vulnerability Zoning Model Research Based on Composite Evaluation
Taking lightning density,incidence of lightning disaster,lightning disaster economic loss rate and the rate of lightning disaster damage as the lightning vulnerability assessment indices,we employed the analytic geometry of linear equation to standardize data and the AHP anlysis method to modify the index data,and finally utilized the cluster analysis to the total value of the vulnerability for a more rational and scientific classification,with Fujian Province as an example for the new model.The results show that the composite evaluation of model calculations is much better mathematically than other methods,and this method can detailedly and completely represent the relation between indices of lightning disaster vulnerability zoning and the combined effects of indices on lightning disaster vulnerability.
