Study on Risk Zoning of Disaster Reduction Capacity of Township Units:Taking a Certain Region in Central Hebei Province as an Example
Taking a certain region in central Hebei Province as an example,an evaluation index system for the integrated disaster management ability,disaster preparedness ability,and self-rescue and transfer capacity of townships(streets)and communities(administrative villages)was constructed.The TOPSIS comprehensive assessment model with the superiority and inferiority solution distance method was applied to quantitatively evaluate the comprehensive disaster reduction ability of the studied area.The mean-standard deviation method of ArcGIS was used to conduct the study of disaster risk area division.The results show that the risk levels of townships(streets)disaster reduction are mainly medium and weaker;The disaster reduction capacity is the strongest in the southeast,slightly stronger in the northwest,followed by the south,west and east,and the weakest in the middle and north regions.The disaster reduction risk levels of communities(administrative villages)are mainly medium levels,and the disaster reduction ability is the strongest in the east,slightly stronger in the west and south,followed by the central and western regions,and the weakest in the north.The evaluation results more accurately identify the advantages and limitations of the disaster reduction capacity of each township,and the differences in disaster reduction capacity are mainly influenced by factors such as material reserves,public hedging,and risk assessment capabilities.
