Abstract:With the accelerating urbanization, the urban heat island effect increasingly threatens ecological well-being. Green spaces such as pocket parks play a vital role in mitigating these effects. Under the background of 'Stock Type' development, pocket parks are becoming a key strategy for enhancing urban livability. This study investigates how different plant community structures influence microclimate regulation in autumn and winter, using Liuhe Garden in Kunming as a case study. Field measurements were conducted at four types of plant configurations and one control site. The temperature-humidity index was used to evaluate thermal comfort, and correlations with microclimate variables were analyzed. Results indicated that cooling and humidifying effects are more pronounced in the afternoon, especially under multi-layered plants communities. Tree-shrub-herb composite communities were most effective in reducing solar radiation. However, in autumn and winter, dense vegetation may reduce human comfort. Based on these findings, in the construction of green space in pocket parks, planning should be based on the local climate characteristics, tailoring interventions to local conditions. Specifically, the appropriate configuration of single-layer plant communities and deciduous trees should be considered.
