Trees and green spaces are part of the environmental systems that are essential to the quality of human life in urban spaces. In general, Brazilian cities have a high proportion of impermeable surfaces which affect the urban microclimate. This paper examined the impact of vegetation presence and configuration on human behavior in three downtown squares in Aracaju, Brazil. The monitored period was summer in 2014–2015. The study collected data on the microclimates of urban squares, conducted surveys of urban features and pedestrian preferences, and developed human behavior maps. Results showed that the green spaces provided more stable microclimates during the day and lower surface temperatures than other urban settings in the squares, which provided a more comfortable thermal environment for people. However, the preferences of pedestrians were not aligned to green spaces in the human behavior maps in two of these squares. It was found that the configuration of the landscape design in squares and surrounding commercial activity influenced human behavior more than the microclimate benefits of vegetation in the urban environment. Urban planning laws can be used to adjust the design and environmental conditions in highly developed urban centers to increase thermal comfort or climate resilience.

树木和绿色空间是环境系统的一部分，对于城市空间中的人类生活质量至关重要。总体而言，巴西城市的不透水表面比例很大，这会影响城市的小气候。本文研究了巴西阿拉卡茹（Aracaju）的三个市中心广场上植被的存在和配置对人类行为的影响。监测期为2014-2015年夏季。这项研究收集了有关城市广场小气候的数据，对城市特征和行人偏好进行了调查，并开发了人类行为图。结果表明，与广场上的其他城市环境相比，绿色空间在白天提供了更稳定的小气候和更低的地表温度，为人们提供了更舒适的热环境。然而，行人的偏好与其中两个广场的人类行为图中的绿色空间不一致。人们发现，在广场和周围商业活动中景观设计的配置对人类行为的影响大于城市环境中植被的微气候效益。城市规划法可用于调整高度发达的城市中心的设计和环境条件，以提高热舒适性或气候适应性。
