| 摘 要： | 随着城市建设用地飞速扩张,绿地作为稀缺资源,对居民心理健康具有重要影响。本文基于2015年广州市1273份居民问卷调查数据,并通过腾讯街景视图和机器学习算法提取街景绿地数据,考察街景绿地、地方依恋和心理健康之间的内在逻辑与机理,并对比本地居民和外来移民的差异。研究发现：① 街景绿地与居民心理健康水平呈显著的正相关关系;② 街景绿地与心理健康的关系受到中介变量地方依恋的影响,即街景绿地通过影响居民地方依恋,间接影响其心理健康水平;③ 对于本地居民,地方依恋发挥完全中介效应,即街景绿地对居民心理健康的影响完全通过地方依恋实现;④ 对于外来移民,地方依恋则发挥部分中介效应,即街景绿地不仅直接作用于居民的心理健康状况,而且通过影响居民的地方依恋间接提升其心理健康水平。

| Abstract: | With the burgeoning development of urbanization, the total population in urban China has increased rapidly in the past decades, resulting in a series of problems such as air pollution, environment degradation and housing shortage. As the arrival of the new urbanization, urban construction and management have gradually reflected the return of humanity, and have increased public attention on urban residents' health. As one of the important dimensions of health, mental health has become the research emphasis of various disciplines. Meanwhile, with the rapid expansion of the urban construction land, green space, as a kind of scarce resource, exerts an important influence on the mental health of urban residents. In this context, based on the questionnaire survey data of 1273 residents from 23 communities of Guangzhou in 2015, this paper unravels how streetscape greenery affects residents' mental health through place attachment. Also, this paper explores and compares the differences in mechanism between the local residents and migrants. Streetscape greenery within a 1000 m circular buffer of each community is extracted from Tencent Street View data by a machine learning approach. The results indicate that: (1) Streetscape greenery of the community can directly improve mental health of the residents. (2) Place attachment mediates the relationship between streetscape greenery of the community and mental health of the residents. Streetscape greenery exerts influence on mental health indirectly through place attachment; (3) For the local residents, the influence of streetscape greenery on mental health is fully mediated by place attachment. That is to say, the effect of streetscape greenery on mental health is fully explained by place attachment. (4) For migrants, place attachment partially mediates the relationship between streetscape greenery and mental health. That is to say, streetscape greenery of the community can directly improve migrants' place attachment, and therefore indirectly improve their level of mental health. At the same time, streetscape greenery can exert a positive effect on residents' mental health directly. The paper reveals the heterogeneity in the mechanism of streetscape greenery on mental health between the local residents and migrants. Based on the empirical findings above, we call for further policy concerns upon the differentiation of different social groups to improve mental health of the residents, especially for migrants. |
