The study takes Chang Le Park, Xing Qinggong Park, and Revolutionary Park in Xi'an as the research subjects, using the Normalized Difference Vegetation Index (NDVI), Normalized Difference Built-up Index (NDBI), and Normalized Difference Water Index (NDWI) to calculate the composition and characteristics of the park's underlying surface elements. The study utilizes ENVI-met for simulating the thermal environment of the parks and performs a multiple linear regression analysis to evaluate the influence of the park's underlying surface on atmospheric temperature. The research indicates that for every 1% increase in vegetation coverage, the temperature decreases by 0.4°C, while for every additional hectare of park area, the temperature decreases by 0.006°C. This study quantitatively reveals the regulatory effect of park surfaces on temperature and provides a scientific basis for urban planning and green space design.
