居民幸福感是影响社会稳定的重要因素，也是新时期中国城市发展的战略目标。拓展大都市中微观尺度的研究，探求居住环境对居民幸福感的影响为建设幸福城市提供科学决策依据。本项目基于地理学空间分层思想，在构建居民幸福感影响机制的多尺度分析框架与方法基础上，以居民幸福感空间分布规律的分析为支撑，揭示中微观尺度居住环境对居民幸福感的影响机制。通过以杭州为例的实证分析，识别影响居民幸福感的关键因素，利用多层级模型确定关键因素的影响范围及最优尺度，构建多尺度空间评价模型，提出针对不同类型区的幸福感提升模式，在实践层面为政府改善居住环境提供更具空间针对性的政策建议。本研究有助于丰富地理学研究幸福感的空间内涵，其成果可以为其他大都市和中小城镇的新型城镇化战略提供借鉴。

Citizens’ subjective well-being is important factor that affect social sustainability, as well as strategic target of urban development in transitional China. Unfortunately, the high growth rate in terms of GDP did not promise an equal improvement on subjective well-being. Rapid urbanization sacrificed citizens’ quality of life, leading to decrease of subjective well-being. Exploring the influence of living environment on citizens’ subjective well-being based on micro scale in mega city is meaningful to offer scientific basis for happy city construction. Based on hierarchy thought of geography, this proposed research will build multilevel theoretical and methodological framework for analyzing the impact of living environment on subjective well-being. The research focus on revealing the spatial distribution pattern of citizens’ subjective well-being and the mechanism of living environment on citizens’ subjective well-being at micro scale. In case of Hangzhou, the study will identify key factors that influencing subjective well-being, based on that, measure the influencing scope and optical scale of factors using multilevel modelling. Finally, the research will establish multiscale spatial evaluation model and conclude with promotion pattern of happiness for different district. The research will shed some light on subjective well-being at micro level, deepen the reflection of the living environment change, and guide the new-type urbanization of mega and small city in China.
