- Abstract:
- We firstly improve the evaluation process of the comprehensive disaster-index method with the entropy weight method and the geometric mean model.Then we select 7 indicators of 4 elements of the disaster losses including casualties,damage to crops,house collapse,and economic losses from the data of 9 major natural disasters in Yunnan Province from 1978 to 2020 according to the statistics of the Emergency Management Department,social-economic statistics released by the statistics department,and using these 7 indicators we build the absolute and relative indexes of comprehensive disaster losses.Finally,we assess and grade the severity of disaster losses with the improved comprehensive disaster-index method.The results suggest that in terms of total disaster losses,Zhaotong City,Qujing City,Wenshan Prefecture in east Yunnan,and Dali Prefecture,Chuxiong Prefecture,and Pu'er City in west Yunnan suffered from heavy losses.In terms of the impact on social economy,Diqing Prefecture,Nujiang Prefecture,Lijiang City,Chuxiong Prefecture and Pu'er City in west Yunnan,and Zhaotong City,Wenshan Prefecture in east Yunnan suffered from heavy losses.The improved comprehensive disaster-index method helps to avoid the arbitrariness in the whole process of weight determination,index calculation and the loss grading; the assessed losses are in line with the real disaster losses.The improved comprehensive disaster-index method is practicable and effective.
