Public participation in ecological civilization construction is a critical pathway for advancing ecological urban design. This study examines residents’ perceptions, satisfaction, and participation in the construction of ecological civilization in Urumqi, northwestern China. Drawing on 1012 questionnaires, this empirical study investigates factors influencing public participation in the construction of ecological civilization. The findings indicate that residents exhibited a strong subjective awareness of public participation in ecological civilization construction (mean score = 4.66), yet ecological cognition (2.75) and participation confidence (2.97) were relatively weak and require further improvement. Satisfaction levels were relatively higher for green status (2.51) and information transparency (2.41), whereas overall satisfaction remained modest, with water resources (1.81) and waste management (1.99) emerging as key concerns. Residents demonstrated a moderate willingness to contribute financially and primarily engaged in low-cost, habitual ecological practices. Significant differences were observed across socio-demographic variables (p < 0.05). Uncivil behaviors and natural pressures were observed as visible obstacles. Strong government leadership, active public engagement, and effective media communication contribute to advancing ecological civilization construction. These results provide valuable insights for promoting ecological civilization construction in northwestern China.
