摘要
伴随中国的快速城市化进程,面向城市可持续发展与更新的生态效益评价研究正获得越来越多的关注.本文立足于中国城市更新实践,旨在优化城市更新生态效益评价方法,构建市民满意度结构方程模型,制定了包含空气质量、热岛效应、植被绿化、资源节约、城市交通、城市空间在内的6个评价指标,并选取西安市幸福林带城市更新项目为研究对象,开展问卷调查,并使用调查结果对评价模型进行拟合修正,综合评价了市民对西安幸福林带城市更新项目生态效益的满意度.研究发现:市民的生态期望与整体期望达成率分别为94.3%和97.4%,市民预期得到较好满足;市民期望对生态效益市民感知具有正向影响,路径系数为0.381;生态效益市民感知对市民满意度有显著正向影响,路径系数为0.903;市民满意度对市民信任有显著正向影响,路径系数为0.955.本研究验证了市民满意度结构方程模型在城市更新生态效益评价中的量化作用,并证明了城市更新应着重提升生态服务质量以改善居民生态环境体验,应推动建立城市更新的生态、经济、社会、人文效益协同的发展机制以及政府、居民、开发商多元主体协同的建设治理机制.
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.
