Abstract:

Aimed to scientifically allocate the earthquake prevention and disaster reduction resources,this paper firstly analyzes the definition of regional earthquake prevention and disaster reduction ability of China from the absolute and relative two levels: The former is a regional function to prevent from earthquake attacking and to reduce disaster losses which are determined by the region's various characteristics such as natural,economic,social and culture conditions,while the latter,based on the former,is the disaster-reduction capacities according to the earthquake disaster loss. Then,the paper constructs the evaluation index system for the absolute ability of China,which includes one object layer,three rule layers,thirteen factor layers and sixteen variable layers. Finally,the study puts forward the comprehensive assessment of absolute ability and relative ability and draws the contribution maps of them. The result shows that there are obvious regional differences of both the absolute ability and the relative ability in China. Meanwhile,there exist obvious regional differences between them. The former shows that the ability in eastern region is generally higher than the national average ability,the central and northwestern areas are equal or lower than it,and Tibetan plateau region is the lowest,which is closely related with the distribution characteristics of different regional economic development levels. While for the latter,either in terms of relative ability against the earthquake deaths or relative ability against earthquake economic loss,the low value areas are concentrated in the North China plain,north-south seismic belt,southeast coast and Northeast China plain,which is mainly determined by the matching pattern between the absolute capabilities and the future earthquake damage.

Key words: regional earthquake prevention and disaster reduction ability of China, evaluation index system, assessment method
