Abstract Urban neighborhood green spaces provide ecosystem services important for sustainable and resilient cities. We examine public preferences for these ecosystem services by conducting a discrete choice experiment in Singapore. The results showed that the public preferred the contributions of neighborhood green spaces in reducing temperature (1, 2, or 3 °C), reducing air pollution (20 or 40 %), and learning in nature. However, they did not prefer noise abatement (10, 20, or 30 dB) and increases of bird, butterfly, and native plant species. Creation of a new neighborhood green space was preferred by people living near parks, but not preferred by those living near nature areas. These results show that diverse public preferences exist for different ecosystem services provided by neighborhood green spaces. In the context of Singapore, the urban heat island effect, to be exacerbated under climate change, and air pollution are perceived to be major environmental problems mitigated by urban vegetation.

热带城市国家高度重视城市绿地减少温度和空气污染

摘要 城市邻里绿地为可持续和有弹性的城市提供重要的生态系统服务。我们通过在新加坡进行离散选择实验来检验公众对这些生态系统服务的偏好。结果表明,公众更喜欢社区绿地在降低温度(1、2 或 3°C)、减少空气污染(20% 或 40%)和在大自然中学习方面的贡献。然而,他们不喜欢减少噪音(10、20 或 30 分贝)和增加鸟类、蝴蝶和本地植物物种。居住在公园附近的人们更喜欢创建新的社区绿地,但居住在自然区域附近的人们并不喜欢。这些结果表明,社区绿地提供的不同生态系统服务存在不同的公众偏好。在新加坡的背景下,
