Comparison of Township Disaster Reduction Capacity Assessment Results Based on Three Methods:A Case Study for 18 Townships in a Certain Distnict of a City
摘要
Abstract
Disaster reduction capacity is a comprehensive capability possessed in the process of regional disas-ter prevention and reduction,emergency rescue,and recovery and reconstruction.Taking the basic survey data of the First National Comprehensive Risk Survey of Natural Disasters in a certain distnict of a city as an example,the disaster reduction capacities of 18 townships in the area are quantitatively assessed using the RSR method,non in-teger RSR method,and TOPSIS method,respectively,and a comparative analysis is made from the five aspects of the practicality of the evaluation model,the size of the value,the rank,the overall trend,and the calculation work-load.The results show that:All of the three methods are suitable for quantitative assessment of regional disaster re-duction capacity,and can be selected based on the purpose and needs of regional evaluation.Overall,the RSR method has the best grading of advantages and disadvantages and the highest information loss,while the TOPSIS method has the lowest information loss and the worst grading of advantages and disadvantages.However,based on the evaluation principle of non integer RSR method,ranking each evaluation index by using the linear interpolation method,there is a linear corresponding relation between the compiled rank and the original index value,it not only overcomes the information loss of the RSR method's source data,but also optimizes the grading of advantages and disadvantages of TOPSIS method.Therefore,the improved non integer RSR method has a moderate information loss and grading of advantages and disadvantages,making it the better choice among the three.The study of non integer RSR method can provide reference for quantitative assessment of disaster reduction capacity.关键词
