Urbanization is the only way to modernize, in accordance with the requirements of the national development of new urbanization until 2020, China's urbanization rate will reach 60%, which is the cities and towns' emergency response and damage prevention put forward higher requirements. Based on this, in order to support the 2015 national science and technology projects as the basis, combined with historical earthquake cases and field research, detailed analysis of urban earthquake disaster in Sichuan regional cities in particular damage characteristics based on specifically for this type of earthquake disaster carrier, from regional coefficient, coefficient earthquake, disaster coefficient three lists 24 factors that affect the index in urban emergency earthquake emergency in an attempt to fully reflect the whole process of urban earthquake emergency, on this basis, these factors on the process, the manner and extent of the emergency were analyzed for some existing factors indicators are widely used to assess the model details the applicable conditions and calculation models.This article introduces the basic principles and calculation step of AHP, and on this basis, establish a hierarchy of factors that influence the disposal of urban earthquake disaster emergency, in principle, follow the independence of the earthquake emergency field of six experts to do a survey, and experts through continuous communication and feedback, to the principle of consistency factor index judgment matrix of AHP satisfied,respectively regional coefficient, coefficient earthquake, disaster coefficient index layer three criteria factors weight calculation and in accordance with the right to a major small sort, the last of the target layer determines the disposal of influencing factors right urban earthquake disaster emergency weight and make intuitive weighting histogram drawn transportation damage, seismic intensity, life-system destruction and public disaster bearing capacity the most important influence factor index town earthquake emergency response, and the four factors in the process and the way in urban earthquake emergency were analyzed.Paper selected six representative towns in Sichuan have different geographical, cultural and economic characteristics, the establishment of the disposal of Urban Earthquake Disaster Emergency key factor recognition model to take advantage of the rough set method, combined with the latest statistical yearbook and expert scoring and qualitative indicators are determined quantitative indicator values, obtained six towns earthquake emergency response factor preference decision tables and advantages distinguish matrix derived factor most satisfactory reduction core attribute is the impact of urban earthquake emergency key factor, and a brief analysis of the key factors mode of action and the extent of the towns in the earthquake disaster emergency.For urban managers, with limited resources, the earthquake disaster emergency key factor in the disposal and targeted response, earthquake emergency response will be to increase efficiency and reduce losses caused by the earthquake the most effective way.
