The evaluation index system of livability perception of residents in rural regions was constructed. Based on the questionnaire survey and in-depth interview of Doumen Town of Zhuhai City, this paper revealed the livability characteristics of rural residents and its influencing factors. The research showed that:① Residents of rural regions were quite satisfied with natural environment and built environment, but less satisfied with public service and infrastructure, and showed the social differentiation in livability perception;② The livability perception evaluation of rural residents was significantly affected by livable factors, showing the decreasing characteristics of “public service factors>social and humanistic environment factors>infrastructure factors>built environment factors>natural environment factors”;③ Individual and family attributes of rural residents were also important factors affecting their livability perception, but less important than the livable factors.展开更多
