Urban green space is thought to contribute to citizen happiness by promoting physical and mental health. Nevertheless, how urban green space and happiness are related across many countries with different socioeconomic conditions has not been explored. By measuring the urban green space score (UGS) from high-resolution satellite imagery of 90 global cities covering 179,168 km and 230 million people in 60 developed countries, we find that the amount of urban green space and GDP are correlated with a nation's happiness level. More specifically, urban green space and GDP are each individually associated with happiness. Yet, only urban green space is related to happiness in the 30 wealthiest countries, whereas GDP alone can explain happiness in the subsequent 30 countries in terms of wealth. We further show that the relationship between urban green space and happiness is mediated by social support and that GDP moderates this relationship. These findings corroborate the importance of maintaining urban green space as a place for social cohesion to support people's happiness.

城市绿地被认为通过促进身心健康来提升市民幸福感。然而，在许多具有不同社会经济条件的国家中，城市绿地与幸福感之间的关系尚未得到探讨。通过对90个全球城市的高分辨率卫星图像进行测量，这些城市覆盖了60个发达国家的179,168平方公里和2.3亿人口，我们发现城市绿地面积和国内生产总值（GDP）与一个国家的幸福水平相关。更具体地说，城市绿地和GDP各自独立地与幸福感相关。然而，在最富裕的30个国家中，只有城市绿地与幸福感相关，而在随后的30个国家中，仅GDP就能从财富角度解释幸福感。我们进一步表明，城市绿地与幸福感之间的关系是由社会支持介导的，并且GDP调节了这种关系。这些发现证实了维护城市绿地作为社会凝聚力场所以支持人们幸福感的重要性。
