Traditional surveys for evaluating perceived park accessibility, usability, and attractiveness are expensive and time-consuming, prompting the adoption of social media data as a viable alternative. This study fine-tuned the Chinese-RoBERTa-wwm-ext model on a specially curated dataset to measure perceived accessibility, usability, and attractiveness across 270 parks in Beijing and Guangzhou through 153,872 online comments. We conducted statistical analyses to uncover temporal patterns and incorporate park perception scores into the 2SFCA method for spatial distribution analysis. Additionally, we utilized XGBoost, SHAP, and PDP to investigate the nonlinear driving mechanisms behind these perceptions. Key findings include: (1) Park visitation demonstrates a strong seasonal pattern, with central urban parks consistently outperforming suburban ones; (2) Central subdistricts might face reduced park services due to high population demands; (3) Accessibility is significantly influenced by ticket pricing and transportation availability, especially bus stations; (4) Usability is optimal at a moderate density of sports and fitness facilities (22 per km<sup>2</sup>) and proximity to residential areas; (5) Attractiveness benefits from closeness to the Central Business District and amenities such as toilets and restaurants, with a critical park size threshold of 9 km<sup>2</sup>.

Green spaces are crucial for mitigating UHIs, yet their expansion is limited. Consequently, optimizing the layout of existing green spaces to maximize their cooling effects is vital. However, the answers of which green space morphology is most beneficial vary across different study areas. This study employs an improved Gaussian kernel geographically weighted random forest (GWRF) model to assess the nonlinear relationship between green spaces morphology and Land Surface Temperature (LST), comparing the performance of this model with three traditional models (OLS, GWR, and RF). The results reveal that green spaces with more complex boundaries, larger individual areas, and concentrated distributions exhibited superior cooling effects. However, the sensitivity to these factors varied across different city functional zones: transportation zones were most influenced by the total area of green spaces, industrial zones by the average size, and commercial zones by the total area and boundary complexity.

This study introduces a novel framework of indicators to comprehensively evaluate the three-dimensional cooling properties of parks, encompassing factors such as intensity, volume, and energy saving potential efficiency. The dynamic three-dimensional changes in the cooling effect and energy saving potential of two representative urban parks selected by multisource remote sensing data were simulated during spring, summer and winter days using the ENVI-met microclimate model. The results show that while seasonal variations impact park cooling and energy saving potential, the differences between individual parks outweigh these variations. Factors such as internal vegetation layout, surrounding building morphology, and prevailing wind direction emerge as pivotal factors on the cooling effects, particularly the cooling volume. Notably, the evaluation indicators exhibit distinct patterns of variation between intraday and seasonal analyses, with energy saving efficiency per unit volume demonstrating greatest stability. Furthermore, the exponential growth in the cumulative energy saving potential observed in the larger parks, despite diminishing returns in energy saving efficiency per unit volume.
