| 摘要 | Pocket parks play a positive role in enhancing the urban thermal environment and human thermal comfort. Existing research mostly emphasizes green space area, vegetation types, and the overall cooling effects of urban parks. However, investigations into the relationship between the internal green space layout pattern within pocket parks and their impact on thermal comfort remain limited. To systematically clarify the relationship between green space layout patterns and human thermal comfort, this study focused on pocket parks within the high-density urban environment of Beijing. The ENVI-met microclimate model was employed to simulate seven distinct green space layout patterns, using an all-hard pavement scenario as the control. The physiological equivalent temperature (PET) was employed to assess human thermal comfort across various scenarios. The findings showed the impact of green space fragmentation degree, shape complexity, and green belt orientation on thermal comfort. It was observed that the average temperature reduction among the seven green space layout patterns was relatively small overall. Altering the green space layout alone proved insufficient to significantly decrease the overall air temperature. In contrast, PET exhibited greater sensitivity to changes in green space layout, particularly indicating a more pronounced improvement in thermal comfort at 07:00 and 18:00. Further analysis indicated that increased fragmentation, edge density, and shape complexity did not necessarily enhance thermal comfort. Instead, the continuity of green spaces, the presence of tree canopy shading, and the organization of ventilation pathways were more critical factors in improving PET. This study offers valuable insights for optimizing the green space layout of pocket parks in Beijing and informs the design of climate-adaptive strategies in high-density urban environments. |
