Even though the interaction between plants and the outdoor wind environment has been a focus of interest for scholars from various disciplines in recent years, the relationship between campus outdoor wind comfort and plant configuration in subtropical coastal areas remains poorly understood. Using the outdoor space of a typical subtropical coastal campus (the Donghai Campus of Quanzhou Normal University) as a case study, we explore the connection between plant configuration and outdoor wind comfort. The campus outdoor area is segmented into roads, squares, and courtyards to investigate this relationship. To achieve this goal, a 9-h fixed-point measurement method and the PHOENICS software (2016) were utilized. The following are the findings of the research: (1) Within the realm of trees, the banyan, Bischofia javanica, and kapok species exhibit a notable impact on wind speed reduction, with respective wind reduction ratios of 1.22, 1.31, and 1.29. Notably, among shrubs, waringin stands out with a wind reduction ratio of 1.83. (2) The tree + shrub + grass combination is the most effective method for reducing wind among the three plant facade configurations. Specifically, the combination of Bischofia javanica, waringin, and carpet grass has the best wind reduction effect, with a wind reduction ratio of 2.55. (3) Adding Bischofia javanica, waringin, and grass plants in areas with high wind speeds can effectively improve wind comfort. This provides directions for creating a comfortable wind environment on university campuses situated in subtropical coastal areas.

Enhancing the wind comfort of outdoor enclosed spaces is crucial for improving visitor satisfaction at the Maritime Silk Road World Heritage site, with the arrangement of its facade being the primary factor influencing outdoor wind comfort. This study examines 50 outdoor enclosed spaces at Kaiyuan Temple in Quanzhou, a Maritime Silk Road World Heritage site, as the research object. Through on-site measurements and CFD simulations, the influence of different outdoor enclosed space facade layouts on winter wind comfort is compared and analyzed. Here are the findings of the research: (1) The height-to-cross-section ratios of 0.37, 0.47, and 0.27 correspond to the best wind speed comfort, wind speed stability, and wind regulation amplitude. (2) Enclosure rates of 0.06, 0.42, and 0.42 are linked to the ideal wind speed comfort, wind speed stability, and wind regulation amplitude. (3) Optimal wind speed comfort, wind speed stability, and wind regulation amplitude are related to a permeability of 0.03, 0.59, and 0.03, respectively. The conclusions above can serve as scientific references for enhancing the wind comfort of outdoor enclosed spaces in the Maritime Silk Road World Heritage sites.
