Abstract: Resilient city construction can effectively enhance urban disaster reduction and recovery capabilities, and intercross and fusion with urban emergency management functions. While, the first responder team system can significantly improve the emergency response capacity of the grassroots and promote the good operation of resilient urban communities. Based on literature review, through questionnaire survey, the current situation of the construction of the first responders at the grass-roots level in an administrative village (community) in Lushan County, Ya’an City, was investigated. Then the practical effect of the first responder system at the grass-roots level was analyzed. The survey found that the grassroots have a clear understanding of the first responder team. They are generally satisfied with their emergency response capabilities and show a strong willingness to participate, but believe that aspects such as rescue equipment and knowledge need to be improved. Practical analysis shows that the first responder system has been basically formed but team building needs to be improved, and the emergency plan system has been established but training and drills still need to be strengthened. In addition, science popularization and education have promoted the public’s emergency response capability. Finally, the paper puts forward improvement measures from five aspects: strengthening government action, enriching training drills, standardizing team construction, building communication platforms, and encouraging public participation.
