Abstract:The urban system is a complex giant system, and its resilience evaluation from the perspec tive of earthquake disaster is crucial for evaluating the earthquake prevention and disaster mitigation ca pability of urban system and the sustainable development of urban and rural areas. Based on the differ ent performance of urban system throughout the entire process of earthquake disaster, the evaluation indicator system of urban resilience from the perspective of earthquake disaster is constructed from four aspects: resistance, response, recovery and adaptability. To address the issues of subjectivity in the weighting of evaluation indicators and the complexity in the evaluation indicator system, the pro jection pursuit method is introduced to analyze the data structure of the indicators, to identify the opti mal projection direction for determining their weights. Combined with the matter-element extension model, the correlation degrees of indicators and the comprehensive correlation degrees of cities are calculated. The evaluation grades of urban resilience from the perspective of earthquake disaster were de termined according to the principle of maximum correlation degree. Taking 7 cities and 3 prefectures in the active seismic belt of Sichuan Province as examples, the rationality and feasibility of the method are verified. The results show that Zigong City, Ya'an City and Liangshan Yi Autonomous Prefecture are generally resilient cities; Deyang City and Mianyang City are higher resilient cities; Luzhou City, Neijiang City and Yibin City are basic resilient cities; Aba Tibetan and Qiang Autonomous Prefecture and Ganzi Tibetan Autonomous Prefecture are silient. The research results can provide refer-ence for the evaluation of urban seismic resilience and offer insights for the sustainable development of urban and rural planning and construction.
