从城市社区居民生活质量的微观视角出发，基于生活质量的客观评价与主观感知的差异性，构建“居民主客观生活质量空间匹配与差异-影响机制-城市空间优化”的关系模型；综合运用RS与GIS技术、问卷调查、探索性因子分析等方法，分别从客观条件与主观感知两方面评价社区居民生活质量，揭示郑州市由中心城区到外围区居民客观评价与主观感知生活质量的空间格局与规律。在此基础上，进一步分析客观评价与主观感知生活质量在空间上的匹配性与差异性，并运用地理加权回归模型（GWR）与结构方程模型(SEM)探究影响居民主客观生活质量空间分异、匹配性与差异性的原因及作用机制，明确居民主客观生活质量与城市功能结构之间作用的关键要素与过程，提出以居民生活质量为导向的城市空间结构优化的模式与对策，为郑州市合理有序地进行新型城镇化建设与可持续发展提供科学依据。

From the micro perspective of residents' quality of life in urban communities，this project attempts to build a relationship model of "subjective and objective quality of life in spatial matching and difference-influencing mechanism-optimizing urban space”. Specifically, the project aims to assess the quality of life from the perspectives of objective conditions and subjective perception respectively, to reveal the spatial pattern and law of subjective and objective quality of life from the center to outskirts in Zhengzhou city. In order to deal with the above research questions, we integratedly employ the RS, GIS, and questionnaire investigation methods. On this basis, this project analyzes the subjective and objective quality of life in space matching and difference, then, the reason and influencing mechanism which affect residents' subjective and objective quality of life are explored by the methods of Geographically Weighted Regression(GWR) and Structure Equation Model(SEM),meanwhile, the key elements and process are clarified between subjective and objective quality of life and urban functional structure. Finally, urban spatial structure optimization model and countermeasures are put forward guided by residents' quality of life, to provide a scientific basis for new-type urbanization and sustainable development of Zhengzhou.
