With the rapid urbanization in China,the evaluation of ecological benefits of urban renewal based on sustainable development has been receiving increasing attention.Based on the practice of urban renewal in China,we constructed a Structural Equation Model (SEM) of citizen satisfaction,which uses six indicators including air quality,heat island effect,vegetation greenery,resource conservation,urban transportation and urban open space to measure the ecological benefits of urban renewal,then carried out a questionnaire to validate the SEM in evaluating citizens' satisfaction with the ecological benefits of Xi'an happiness forest belt urban renewal project.The study shows that most of the citizens' expectation can be met as the achievement rates of ecological expectation and overall expectation of citizens for Xi'an happiness forest belt urban renewal project were 94.3％ and 97.4％,respectively.Citizen expectation has a positive impact on citizen perception of ecological benefits,and the path coefficient is 0.381;citizen perception of ecological benefits has a significant positive impact on citizen satisfaction,and the path coefficient is 0.903;and citizen satisfaction has a significant positive impact on citizen trust,and the path coefficient is 0.955.It can be concluded that the proposed SEM of citizen satisfaction can quantitatively evaluate the ecological benefit of urban renewal.Furthermore,the quality of ecological services should be focused in future urban renewal to improve residents' ecological environment experience,and efforts should be made to promote the coordinated consideration of ecological,economic,social and cultural benefits of urban renewal,as well as the collaborative incorporation of multiple stakeholders such as government agencies,local residents and property development firms in urban renewal.
